     FIELD OF THE INVENTION 
     The present invention relates to a method for manufacturing a shoe embryo and an associated shoe embryo, and particularly to a method for manufacturing a shoe embryo tailored from a tubular fabric and an associated shoe embryo. 
     BACKGROUND OF THE INVENTION 
     A shoe in general includes two parts—a shoe upper and a sole. The sole is secured below the shoe upper. A material of the shoe upper focuses on providing comfort and firmness. For example, there are diversified choices of materials having different properties for the shoe upper of sports shoes. The so-called “different properties” include tensile resistance, wear resistance, flexibility, air permeability, compressibility, moisture absorption and quick perspiration drying. More specifically, the shoe upper may be formed by materials including textiles, leather, synthetic leather or rubber. Common materials for making the commercial shoe upper include textiles, polymer foams, polymer sheets, leather and synthetic leather. However, one of the most common base materials for making the shoe upper or sports shoes or the shoe upper of casual shoes is fabrics manufactured from yarns of composite materials by a weaving machine. Once such fabric is formed three-dimensionally, a shoe embryo is formed. One main reason that the shoe embryo is extensively applied as the base material of sports shoes or casual shoes is that, the shoe embryo can be given different properties in different areas, including functional purposes of tensile resistance, wear resistance, flexibility, air permeability, compressibility, comfort, and moisture absorption. It is thus known from above, the shoe embryo is a semi-finished product before such shoes are completely manufactured. That is to say, the shoe embryo requires further subsequent processes, such as inserting a vamp model for shaping, surface ironing, gluing/heating/pressurizing, paint spraying and dye, sole gluing and extracting the vamp model. In current technologies for the shoe embryo, e.g., the Taiwan Patent No. M515792, a three-dimensional shoe embryo is generally formed by combining, splicing and sewing multiple different planar fabrics. However, the technical means for manufacturing the shoe embryo suffers from certain drawbacks that need to be overcome. First of all, to re-organize, splice and sew different planar fabrics to form a three-dimensional shoe embryo, an operating staff is required to have sophisticated techniques and capabilities, which can only be achieved through professional tailor training, hence inevitably leading to significant manpower costs for manufacturers. Secondly, when the planar fabrics are re-organized, spliced and sewn, deformation of the shoe embryo and splicing deviations may likely occur due to human factors such as alignment errors, in a way that the yield rate of the shoe embryo may not be effectively increased and material costs are substantially increased for manufacturers. Thirdly, processes for combining and splicing the planar fabrics are tedious, which limits both production efficiency and production throughput. 
     SUMMARY OF THE INVENTION 
     In view of the above drawbacks of known technologies, it is a primary object of the present invention to shorten work hours, boost production efficiency, increase product yield rate and reduce manpower costs to achieve enhanced industry competitiveness. 
     To achieve the above object, the present invention provides a method for manufacturing a shoe embryo tailored from a tubular fabric. The method includes: providing at least two yarns to weave and form a tubular fabric, weaving a toe portion tailor auxiliary line at one end of the tubular fabric and a heel portion tailor auxiliary line at the other end, and weaving an ankle portion tailor auxiliary line at a position between the heel portion tailor auxiliary line and the toe portion tailor auxiliary line and near the heel portion tailor auxiliary line, wherein the tubular fabric is sequentially defined into a toe portion trimmed region, an ankle portion trimmed region and a heel portion trimmed region by the toe portion tailor auxiliary line, the ankle portion tailor auxiliary line and the heel portion tailor auxiliary line, respectively; trimming and removing the ankle portion trimmed region, and performing an overlock process according to the ankle portion tailor auxiliary line to form an ankle opening overlock line at the tubular fabric; trimming and removing the heel portion trimmed region, and performing an overlock process according to the heel portion tailor auxiliary line to form a heel overlock line at the tubular fabric; folding below the heel overlock line to form a concave crease and a revealed crease, such that a sole trimmed region is defined at the tubular fabric by the concave crease and the revealed crease; trimming and removing the sole trimmed region, and performing an overlock process according to the concave crease to form a sole overlock line at the tubular fabric; trimming and removing the toe portion trimmed region, and combining the toe portion tailor auxiliary line in an overlapping manner for an overlock process to form a toe cap overlock line at the tubular fabric; and performing shaping to form a shoe embryo including an ankle portion, a heel portion, a toe cap portion and a sole portion.

     To achieve the above object, the present invention further provides a shoe embryo tailored and manufactured from a tubular fabric. The shoe embryo is tailored from a tubular fabric, and includes a sole portion, a toe cap portion located at one end of the sole portion, an ankle portion located at the other end of the sole portion, and a heel portion located above the sole portion and near the heel portion.

     Further, in the shoe embryo tailored and manufactured from a tubular fabric, a joint of the ankle portion and the heel portion is extended to form a shoe upper. 
     To achieve the above object, the present invention further discloses a method for manufacturing a shoe embryo tailored from a tubular fabric. The method includes: providing at least two yarns to weave and form a tubular fabric, weaving a toe portion tailor auxiliary line at one end of the tubular fabric and weaving a lining sealing auxiliary line at the other end, weaving a heel portion tailor auxiliary line at a center between the toe portion tailor auxiliary line and the lining sealing auxiliary line to define a lining fabric between the heel portion tailor auxiliary line and the lining sealing tailor auxiliary line, and weaving an ankle portion tailor auxiliary line at a position between the heel portion tailor auxiliary line and the toe portion tailor auxiliary line and near the heel portion tailor auxiliary line, wherein the tubular fabric is sequentially defined into a toe portion trimmed region, an ankle portion trimmed region, a heel portion trimmed region and a lining trimmed region by the toe portion tailor auxiliary line, the ankle portion tailor auxiliary line, the heel portion tailor auxiliary line and the lining seal auxiliary line, respectively; trimming and removing the lining trimmed region, and combining the lining sealing auxiliary line in an overlapping manner for an overlock process to form a lining overlock line at the tubular fabric; folding the lining fabric in reverse into the tubular fabric using the heel portion tailor auxiliary line as a basis; together trimming and removing the ankle portion trimmed region and a part of the lining fabric corresponding to the ankle portion trimmed region, and performing an overlock process jointly with the lining fabric according to the ankle portion tailor auxiliary line to form an ankle opening overlock line at the tubular fabric; together trimming and removing the heel portion trimmed region and a part of the lining fabric corresponding to the heel portion trimmed region, and performing an overlock process jointly with the lining fabric according to the heel portion tailor auxiliary line to form a heel overlock line at the tubular fabric; folding below the heel overlock line to form a concave crease and a revealed crease, such that a sole trimmed region is defined at the tubular fabric by the concave crease and the revealed crease; trimming and removing the sole trimmed region, and performing an overlock process according to the concave crease to form a sole overlock line at the tubular fabric; trimming and removing the toe portion trimmed region, and combining the toe portion tailor auxiliary line in an overlapping manner for an overlock process to form a toe cap overlock line; and performing shaping to form a shoe embryo including an ankle portion, a heel portion, a toe cap portion and a sole portion as well as the lining fabric therein.

     Further, in the method for manufacturing a shoe embryo from tailoring a tubular fabric, the lining sealing auxiliary line, the ankle portion tailor auxiliary line, the heel portion tailor auxiliary line and the toe portion tailor auxiliary line are selected and woven from at least one of the yarns used for weaving the tubular fabric. 
     Further, in the method for manufacturing a shoe embryo from tailoring a tubular fabric, the lining sealing auxiliary line, the ankle portion tailor auxiliary line, the heel portion tailor auxiliary line and the toe portion tailor auxiliary line are selected and woven from at least one of the colors of the yarns used for weaving the tubular fabric.

Further, the lining sealing auxiliary line includes an arched upper auxiliary segment and an arched lower auxiliary segment connected to two ends of the upper auxiliary segment. 
     Further, in the method for manufacturing a shoe embryo from tailoring a tubular fabric, the length of the upper auxiliary segment is greater than or equal to the length of the lower auxiliary segment. 
     To achieve the above object, the present invention further provides a shoe embryo manufactured and tailored from a tubular fabric. The shoe embryo is tailored from a tubular fabric, and is characterized that, the shoe embryo includes a lining fabric having a front end combined in an overlapping manner and overlocked therein, a sole portion, a toe cap portion located at one end of the sole portion, an ankle portion located at the other end of the sole portion, and a heel portion located above the sole portion and near the heel portion; the ankle portion includes an ankle opening overlock line formed by together trimming and overlocking the tubular fabric and the lining fabric; the heel portion includes a heel overlock line formed by together trimming and overlocking the tubular fabric and the lining fabric, and a sole overlock line formed by folding below the heel overlock line and overlocking.

     Further, in the shoe embryo tailored and manufactured from a tubular fabric, a joint of the ankle portion and the heel portion is extended to form a shoe upper. 
     With the technical solution above, the present invention achieves effects below as opposed to currently known technologies. First of all, as the tubular fabric of the present invention is directly sewn using a three-dimensional shape, and involves no re-organizing, splicing and sewing processes. In the process of trimming and overlocking the tubular fabric in the tubular three-dimensional shape, the issue of error and deviation are unlikely to occur, such that not only the yield rate of the shoe embryo can be promoted without causing a waste in material costs, but also such process of trimming and overlocking can be performed by operators without professional tailor training, thereby helping in reducing manpower costs. Secondly, in the present invention, auxiliary lines apparently visible are woven on the tubular fabric to assist a process operator to perform trimming and overlocking. Thus, an operator may promptly position and process according to exact positions of these auxiliary lines to further optimize production efficiency. Thirdly, with the shoe embryo that is manufactured from the tubular fabric in a tubular three-dimensional shape, re-organizing and splicing processes in currently known technologies can be eliminated. As the processes are simplified, the work hours required for production are also shortened, which further accounts for a factor for effectively enhancing production efficiency and industry competitiveness.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Details of a method for manufacturing a shoe embryo tailored from a tubular fabric and a shoe embryo of the present invention are given in the non-limiting embodiments with the accompanying drawings below. 
       FIG. 1  to  FIG. 11  show schematic diagrams of a first embodiment. In this embodiment, a tubular fabric  1  is woven from at least two yarns. As seen from  FIG. 1  to  FIG. 5 , the tubular fabric  1  has its one end woven with a toe portion tailor auxiliary line  40  and the other end woven with a heel portion tailor auxiliary line  30 . An ankle portion tailor auxiliary line  20  is woven at a position between the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  and near the heel portion tailor auxiliary line  30 . The tubular fabric  1  is sequentially defined into a toe portion trimmed region  41 , an ankle portion trimmed region  21  and a heel portion trimmed region  31  by the toe portion tailor auxiliary line  40 , the ankle portion tailor auxiliary line  20  and the heel portion tailor auxiliary line  30 , respectively. First of all, the ankle portion trimmed region  21  is trimmed and removed, and an overlock process is performed according to the ankle portion tailor auxiliary line  20  to form an ankle opening overlock line  211  at the tubular fabric  1 , as shown in  FIG. 6 . The heel portion trimmed region  31  is trimmed and removed, and an overlock process is performed according to the heel portion tailor auxiliary line  30  to form a heel overlock line  311  at the tubular fabric  1 , as shown in  FIG. 7 . Next, a part below the heel overlock line  311  is folded to form a concave crease  312  and a revealed crease  313 , such that a sole trimmed region  314  is defined at the tubular fabric  1  by the concave crease  312  and the revealed crease  313 , as shown in  FIG. 8 . Next, the sole trimmed region  314  is trimmed and removed, and an overlock process is performed according to the concave crease  312  to form a sole overlock line  315  at the tubular fabric  1 , as shown in  FIG. 9 . The toe portion trimmed region  41  is then trimmed and removed, and the toe portion tailor auxiliary line  40  is combined in an overlapping manner for an overlock process to form a toe cap overlock line  411 . Further, the tubular fabric  1  is shaped into a shoe embryo  10  including an ankle portion  22 , a heel portion  32 , a toe cap portion  42  and a sole portion  50 , as shown in  FIG. 10 . The shoe embryo  10  may then be used for subsequent shoe manufacturing processes. Alternatively, in  FIG. 11 , the shoe embryo  10  may be entirely turned inside out for subsequent shoe manufacturing processes. It should be noted that, concerning the sequences for forming the overlock lines by the trimming and overlock processes, the toe cap overlock line  411 , the ankle opening overlock line  211 , the heel overlock line  311  and the sole overlock line  315  may be sequentially formed by the respective trimming and overlock processes. Further, the tubular fabric  1  is woven from at least two differently-colored yarns, and the ankle portion tailor auxiliary line  20 , the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  may be selected and woven from one of the yarns used for weaving the tubular fabric  1 . Further, the ankle portion tailor auxiliary line  20 , the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  may be selected and woven from one of the colors of the yarns used for weaving the tubular fabric  1 . That is to say, the ankle portion tailor auxiliary line  20 , the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  may be woven from one of the yarns or one of the colors of the yarns used for weaving the tubular fabric  1 . It should be noted that, the toe portion tailor auxiliary line  40  includes an arched above-toe auxiliary segment  401 , and an arched below-toe auxiliary segment  402  connected to two ends of the above-toe auxiliary segment  401 . The length of the above-toe auxiliary segment  401  is greater than the length of the below-toe auxiliary segment  402 , which is beneficial for the toe cap overlock line  411  to form within the range of the sole portion  50 . Thus, when later incorporated with a sole material (a generally known shoe manufacturing process, not shown in the drawing), the toe cap overlock line  411  may be easily concealed and adorned. 
     Again referring to  FIG. 1 ,  FIG. 10  and  FIG. 11 , the shoe embryo  10  in the drawings according to the first embodiment is tailored and manufactured from a tubular fabric  1 , which is woven from at least two yarns. The tubular fabric  1  has its one end woven with the toe portion tailor auxiliary line  40  and its other end woven with the heel portion tailor auxiliary line  30 , and the ankle portion tailor auxiliary line  20  is woven at a position between the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  and near the heel portion tailor auxiliary line  30 . The tubular fabric  1  is sequentially defined into the toe portion trimmed region  41 , the ankle portion trimmed region  21  and the heel portion trimmed region  31  by the toe portion tailor auxiliary line  40 , the ankle portion tailor auxiliary line  20  and the heel portion tailor auxiliary line  30 , respectively. The shoe embryo  10  includes the sole portion  50 , the toe cap portion  42  located at one end of the sole portion  50 , the heel portion  32  located at the other end of the sole portion  50 , and the ankle portion  22  located above the sole portion  50  and near the heel portion  32 . The ankle portion  22  includes the ankle opening overlock line  211  formed by trimming the ankle portion trimmed region  21  of the tubular fabric  1  and overlocking. The heel portion  32  includes the heel overlock line  311  formed by trimming the heel portion trimmed region  31  of the tubular fabric  1  and overlocking, and the sole overlock line  315  formed by folding below the heel overlock line  311  and overlocking. The toe cap portion  42  includes the toe cap overlock line  411  formed by trimming the toe portion trimmed region  41  of the tubular fabric  1  and overlocking. Thus, the shoe embryo  10  may be used for shoe manufacturing processes. 
       FIG. 12  to  FIG. 19  show schematic diagrams of a second embodiment of the present invention. In this embodiment, the tubular fabric  1  is woven from at least two yarns. As seen from  FIG. 12  to  FIG. 14 , the tubular fabric  1  has its one end woven with a toe portion tailor auxiliary line  40  and the other end woven with the heel portion tailor auxiliary line  30 . The ankle portion tailor auxiliary line  20  is woven at a position between the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  and near the heel portion tailor auxiliary line  30 . The tubular fabric  1  is sequentially defined into the toe portion trimmed region  41 , the ankle portion trimmed region  21  and the heel portion trimmed region  31  by the toe portion tailor auxiliary line  40 , the ankle portion tailor auxiliary line  20  and the heel portion tailor auxiliary line  30 , respectively. It is clearly seen that the path design of the ankle portion tailor auxiliary line  20  of the second embodiment is different from the path design of the ankle portion tailor auxiliary line  20  of the first embodiment (also referring to  FIG. 1  to  FIG. 5 ). Thus, to satisfy market demands, the ankle portion trimmed region  21  defined in the second embodiment and the first embodiment may generate different shapes and variations. First of all, the ankle portion trimmed region  21  is trimmed and removed, and an overlock process is performed according to the ankle portion tailor auxiliary line  20  to form the ankle opening overlock line  211  at the tubular fabric  1 , as shown in  15 . The heel portion trimmed region  31  is trimmed and removed, and an overlock process is performed according to the heel portion tailor auxiliary line  30  to form the heel overlock line  311  at the tubular fabric  1 . Because the path design of the heel portion tailor auxiliary line  30  does not connect to the path of the ankle portion tailor auxiliary line  20 , after the ankle opening overlock line  211  and the heel overlock line  311  are formed by sequentially trimming and overlock processes, a joint of the ankle portion  22  and the heel portion  32  may be extended to form a shoe upper  33 , as shown in  FIG. 16 . A part below the heel overlock line  311  is folded to form the concave crease  312  and the revealed crease  313 , such that the sole trimmed region  314  is defined at the tubular fabric  1  by the concave crease  312  and the revealed crease  313 , as shown in  FIG. 17 . Next, the sole trimmed region  314  is trimmed and removed, and an overlock process is performed according to the concave crease  312  to form the sole overlock line  315  at the tubular fabric  1 , as shown in  FIG. 18 . The toe portion trimmed region  41  is then trimmed and removed, the toe portion tailor auxiliary line  40  is combined in an overlapping manner for an overlock process to form the toe cap overlock line  411 . Further, the tubular fabric  1  is shaped into the shoe embryo  10  including the ankle portion  22 , the heel portion  32 , the toe cap portion  42  and the sole portion  50 , as shown in  FIG. 19 . The shoe embryo  10  may then be used for subsequent shoe manufacturing processes. It should be noted that, concerning the sequences for forming the overlock lines by the trimming and overlock processes, the toe cap overlock line  411 , the ankle opening overlock line  211 , the heel overlock line  311  and the sole overlock line  315  may be sequentially formed by the respective trimming and overlock processes. Further, the tubular fabric  1  is woven from at least two differently-colored yarns, and the ankle portion tailor auxiliary line  20 , the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  may be selected and woven from one of the yarns used for weaving the tubular fabric  1 . Further, the ankle portion tailor auxiliary line  20 , the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  may be selected and woven from one of the colors of the yarns used for weaving the tubular fabric  1 . That is to say, the ankle portion tailor auxiliary line  20 , the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  may be woven from one of the yarns or one of the colors of the yarns used for weaving the tubular fabric  1 . It should be noted that, the toe portion tailor auxiliary line  40  includes the arched above-toe auxiliary segment  401 , and the arched below-toe auxiliary segment  402  connected to the two ends of the above-toe auxiliary segment  401 . The length of the above-toe auxiliary segment  401  is greater than the length of the below-toe auxiliary segment  402 , which is beneficial for the toe cap overlock line  411  to form within the range of the sole portion  50 . Thus, when later incorporated with a sole material (a generally known shoe manufacturing process, not shown in the drawing), the toe cap overlock line  411  may be easily concealed and adorned. 
     Again referring to  FIG. 12  and  FIG. 19 , the shoe embryo  10  in the drawings according to the second embodiment is tailored and manufactured from the tubular fabric  1 , which is woven from at least two yarns. The tubular fabric  1  has its one end woven with the toe portion tailor auxiliary line  40  and its other end woven with the heel portion tailor auxiliary line  30 , and the ankle portion tailor auxiliary line  20  is woven at a position between the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  and near the heel portion tailor auxiliary line  30 . The tubular fabric  1  is sequentially defined into the toe portion trimmed region  41 , the ankle portion trimmed region  21  and the heel portion trimmed region  31  by the toe portion tailor auxiliary line  40 , the ankle portion tailor auxiliary line  20  and the heel portion tailor auxiliary line  30 , respectively. The shoe embryo  10  includes the sole portion  50 , the toe cap portion  42  located at one end of the sole portion  50 , the heel portion  32  located at the other end of the sole portion  50 , and the ankle portion  22  located above the sole portion  50  and near the heel portion  32 . The ankle portion  22  includes the ankle opening overlock line  211  formed by trimming the ankle portion trimmed region  21  of the tubular fabric  1  and overlocking. The heel portion  32  includes the heel overlock line  311  formed by trimming the heel portion trimmed region  31  of the tubular fabric  1  and overlocking, and the sole overlock line  315  formed by folding below the heel overlock line  311  and overlocking. The toe cap portion  42  includes the toe cap overlock line  411  formed by trimming the toe portion trimmed region  41  of the tubular fabric  1  and overlocking. The joint of the ankle portion  22  and the heel portion  32  is extended to form the shoe upper  33 . Thus, the shoe embryo  10  may be used for shoe manufacturing processes. 
       FIG. 20  to  FIG. 29  show schematic diagrams of a third embodiment of the present invention. In this embodiment, the tubular fabric  1  is woven from at least two yarns. As seen from  FIG. 20  to  FIG. 22 , the tubular fabric  1  has its one end woven with a toe portion tailor auxiliary line  40 , and the other end woven with a lining sealing auxiliary line  12 . The heel portion tailor auxiliary line  30  is woven at a center between the toe portion tailor auxiliary line  40  and the lining sealing auxiliary line  12 , such that a lining fabric  11  is defined between the heel portion tailor auxiliary line  30  and the lining sealing auxiliary line  12 . The ankle portion tailor auxiliary line  20  is woven at a position between the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  and near the heel portion tailor auxiliary line  30 . The tubular fabric  1  is sequentially defined into the toe portion trimmed region  41 , the ankle portion trimmed region  21 , the heel portion trimmed region  31  and a lining trimmed region  13  by the toe portion tailor auxiliary line  40 , the ankle portion tailor auxiliary line  20 , the heel portion tailor auxiliary line  30  and the lining sealing auxiliary line  12 , respectively. First of all, the lining trimmed region  13  is trimmed and removed, and the lining sealing auxiliary line  12  is combined in an overlapping manner for an overlock process to form a lining overlock line  14  at the tubular fabric  1 , as shown in  FIG. 23 . Using the heel portion tailor auxiliary line  30  as a basis (i.e., when the heel portion tailor auxiliary line  30  is woven, a segment serving as a basis may be woven at an appropriate position of the heel portion tailor auxiliary line  30 ), the lining fabric  11  is folded in reverse into the tubular fabric  1 , as shown in  FIG. 24 . The ankle portion trimmed region  21  and a part of the lining fabric  11  corresponding to the ankle portion trimmed region  21  are together trimmed and removed, and an overlock process is performed jointly with the lining fabric  11  according to the ankle portion tailor auxiliary line  20  to form the ankle opening overlock line  211  at the tubular fabric  1 , as shown in  FIG. 25 . The heel portion trimmed region  31  and a part of the lining fabric  11  corresponding to the heel portion trimmed region  31  are together trimmed and removed, and an overlock process is performed jointly with the lining fabric  11  according to the heel portion tailor auxiliary line  30  to form the heel overlock line  311  at the tubular fabric  1 , as shown in  FIG. 26 . A part below the heel overlock line  311  is folded to form the concave crease  312  and the revealed crease  313 , such that the sole trimmed region  314  is defined at the tubular fabric  1  by the concave crease  312  and the revealed crease  313 , as shown in  FIG. 27 . Next, the sole trimmed region  314  is trimmed and removed, and an overlock process is performed according to the concave crease  312  to form the sole overlock line  315  at the tubular fabric  1 , as shown in  FIG. 28 . The toe portion trimmed region  41  is then trimmed and removed, and the toe portion tailor auxiliary line  40  is combined in an overlapping manner for an overlock process to form the toe cap overlock line  411 . Further, the tubular fabric  1  is shaped into the shoe embryo  10  including the ankle portion  22 , the heel portion  32 , the toe cap portion  42  and the sole portion  50  as well as the lining fabric  11  therein, as shown in  FIG. 29 . The shoe embryo  10  may then be used for subsequent shoe manufacturing processes. It should be noted that, after the lining fabric  11  is folded in reverse and placed into the tubular fabric  1 , concerning the sequences for forming the overlock lines by the trimming and overlock processes, the toe cap overlock line  411 , the ankle opening overlock line  211 , the heel overlock line  311  and the sole overlock line  315  may be sequentially formed by the respective trimming and overlock processes. Further, the tubular fabric  1  is woven from at least two differently-colored yarns, and the lining sealing auxiliary line  12 , the ankle portion tailor auxiliary line  20 , the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  may be selected and woven from one of the yarns used for weaving the tubular fabric  1 . Further, the lining sealing auxiliary line  12 , the ankle portion tailor auxiliary line  20 , the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  may be selected and woven from one of the colors of the yarns used for weaving the tubular fabric  1 . That is to say, the lining sealing auxiliary line  12 , the ankle portion tailor auxiliary line  20 , the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  may be may be woven from one of the yarns or one of the colors of the yarns used for weaving the tubular fabric  1 . It should be noted that, the toe portion tailor auxiliary line  40  includes the arched above-toe auxiliary segment  401 , and the arched below-toe auxiliary segment  402  connected to the two ends of the above-toe auxiliary segment  401 . The length of the above-toe auxiliary segment  401  is greater than the length of the below-toe auxiliary segment  402 , which is beneficial for the toe cap overlock line  411  to form within the range of the sole portion  50 . Thus, when later incorporated with a sole material (a generally known shoe manufacturing process, not shown in the drawing), the toe cap overlock line  411  may be easily concealed and adorned. Further, the lining sealing auxiliary line  12  includes an arched upper auxiliary segment  121 , and an arched lower auxiliary segment  122  connected to two ends of the upper auxiliary segment  121 . The length of the upper auxiliary segment  121  is greater than or equal to the length of the lower auxiliary segment  122 . That is to say, when length of the upper auxiliary segment  121  is equal to the length of the lower auxiliary segment  122 , the upper auxiliary segment  121  is allowed to more easily combine with the lower auxiliary segment  122  in an overlapping manner for an overlock process to form the lining overlock line  14  (as shown in  FIG. 23 ). Since the lining overlock line  14  is placed into the tubular fabric  1 , the position of the lining overlock line  14  does not affect the appearance of the shoe embryo  10  formed from the tubular fabric  1 . Alternatively, the length of the upper auxiliary segment  121  may also be greater than the length of the lower auxiliary segment  122 , such that the lining overlock line  14  may be formed on the sole portion  50  inside the shoe embryo  10 . It should be noted that, when the heel overlock line  311  of the third embodiment of the present invention is sewn according to the path of the second embodiment, the joint of the ankle portion  22  and the heel portion  32  of the third embodiment may also be extended to form the shoe upper  33 , as shown in  FIG. 16  to  FIG. 19  of the second embodiment. 
     Again referring to  FIG. 20  and  FIG. 29 , the shoe embryo  10  according to the third embodiment is tailored and manufactured from the tubular fabric  1 , which is woven from at least two yarns. The tubular fabric  1  has its one end woven with the toe portion tailor auxiliary line  40 , and its other end woven with the lining sealing auxiliary line  12 . The heel portion tailor auxiliary line  30  is woven at the center of the toe portion tailor auxiliary line  40  and the lining sealing auxiliary line  12 , and the lining fabric  11  is defined between the heel portion tailor auxiliary line  30  and the lining sealing auxiliary line  12 . The ankle portion tailor auxiliary line  20  is woven at a position between the heel portion tailor auxiliary line  30  and the toe portion tailor auxiliary line  40  and near the heel portion tailor auxiliary line  30 . The tubular fabric  1  is sequentially defined into the toe portion trimmed region  41 , the ankle portion trimmed region  21 , the heel portion trimmed region  31  and the lining trimmed region  13  by the toe portion tailor auxiliary line  40 , the ankle portion tailor auxiliary line  20 , the heel portion tailor auxiliary line  30  and the lining sealing auxiliary line  12 , respectively. The shoe embryo  10  internally includes the lining fabric  11 , whose front end is trimmed as the lining trimmed region  13  and is combined in an overlapping manner and overlocked. The shoe embryo  10  further includes the sole portion  50 , the toe cap portion  42  located at one end of the sole portion  50 , the heel portion  32  located at the other end of the sole portion  50 , and the ankle portion  22  located above the sole portion  50  and near the heel portion  32 . The ankle portion  22  includes the ankle opening overlock line  211  formed by together trimming the ankle portion trimmed region  21  of the tubular fabric  1  and the lining fabric  11  and overlocking. The heel portion  32  includes the heel overlock line  311  formed by together trimming the heel portion trimmed region  31  of the tubular fabric  1  and the lining fabric  11  and overlocking, and the sole overlock line  315  formed by folding below the heel overlock line  311  and overlocking. The toe cap portion  42  includes the toe cap overlock line  411  formed by trimming the toe portion trimmed region  41  of the tubular fabric  1  and overlocking. Thus, the shoe embryo  10  may be used for shoe manufacturing processes.
