                         302 OF THE SARBANES OXLEY ACT


I, Kexi Xu, certify that:

(1) I have reviewed this annual report on form 10-KSB of Jointland Development,
Inc.;

(2) Based on my knowledge,  this report does not contain any untrue statement of
a  material  fact  or omit  to  state a  material  fact  necessary  to make  the
statements made, in light of the circumstances  under which such statements were
made, not misleading with respect to the period covered by this report;

(3)  Based on my  knowledge,  the  financial  statements,  and  other  financial
information included in this report, fairly present in all material respects the
financial condition,  results of operations and cash flows of the small business
issuer as of, and for, the periods presented in this report;

(4)  The  small  business  issuer's  other  certifying   officer(s)  and  I  are
responsible for establishing and maintaining  disclosure controls and procedures
(as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal  control
over  financial  reporting  (as  defined in  Exchange  Act Rules  13a-15(f)  and
15d-15(f)) for the small business issuer and have:

        (a)    Designed such disclosure controls and procedures,  or caused such
               disclosure  controls  and  procedures  to be  designed  under our
               supervision,  to ensure that material information relating to the
               small business issuer,  including its consolidated  subsidiaries,
               is made known to us by others within those entities, particularly
               during the period in which this report is being prepared;

        (b)    Designed  such  internal  control over  financial  reporting,  or
               caused such  internal  control  over  financial  reporting  to be
               designed under our supervision,  to provide reasonable  assurance
               regarding  the   reliability  of  financial   reporting  and  the
               preparation  of financial  statements  for  external  purposes in
               accordance with generally accepted accounting principles;

        (c)    Evaluated  the  effectiveness  of  the  small  business  issuer's
               disclosure  controls and  procedures and presented in this report
               our  conclusions   about  the  effectiveness  of  the  disclosure
               controls and  procedures,  as of the end of the period covered by
               this report based on such evaluation; and

        (d)    Disclosed  in  this  report  any  change  in the  small  business
               issuer's internal control over financial  reporting that occurred
               during the small  business  issuer's most recent  fiscal  quarter
               (the small business issuer's fourth fiscal quarter in the case of
               an annual report) that has materially affected,  or is reasonably
               likely to materially affect, the small business issuer's internal
               control over financial reporting; and

<PAGE>

(5)  The  small  business  issuer's  other  certifying  officer(s)  and  I  have
disclosed,  based  on our  most  recent  evaluation  of  internal  control  over
financial  reporting,  to the small  business  issuer's  auditors  and the audit
committee  of the  small  business  issuer's  board  of  directors  (or  persons
performing the equivalent functions):

         (a)   All  significant  deficiencies  and  material  weaknesses  in the
               design or operation of internal control over financial  reporting
               which  are  reasonably  likely  to  adversely  affect  the  small
               business  issuer's  ability to  record,  process,  summarize  and
               report financial information; and

        (b)    Any fraud,  whether or not material,  that involves management or
               other employees who have a significant role in the small business
               issuer's internal control over financial reporting.
