Several Ming Dynasty texts list  what were claimed as the Nine Offspring of the Dragon (), and subsequently these feature prominently in popular Chinese stories and writings. , quoting Xie Zhaozhe (, 1567–1624) in his work "Wu Za Zu" (, ca. 1592) gives the following listing in order of oldest to youngest: A well-known work of the end of the sixteenth century, the "Wuzazu" , informs us about the nine different young of the dragon, whose shapes are used as ornaments according to their nature. Further, the same author enumerates nine other kinds of dragons, which used as ornamental decoration or as part of classical Chinese architecture. These examples  can be found architecture throughout Asia used for adorning key-holes, on roofing, incense burners, door knockers, bridges, etc. The "Sheng'an waiji" () collection by the poet Yang Shen (, 1488–1559) gives different 5th and 9th names for the dragon's nine children: the "tāo tiè" (), form of beasts, which loves to eat and is found on food-related wares, and the "jiāo tú" (), which looks like a conch or clam, does not like to be disturbed, and is used on the front door or the doorstep. Yang's list is "bì xì", "chī wěn" or "cháo fēng", "pú láo", "bì àn , tāo tiè", "qiú niú", "yá zì", "suān ní", and "jiāo tú".

The number nine is special in China as it is the largest possible single digit, and Chinese dragons are frequently connected with it. For example, a Chinese dragon is normally described in terms of nine attributes and usually has 117 (9x13) scales - 81 (9x9) Yang and 36 (9x4) Yin. This is also why there are nine forms of  the dragon and there are 9 sons of the dragon. The Nine-Dragon Wall is a spirit wall with images of nine different dragons, and is found in imperial Chinese palaces and gardens. Because nine was considered the number of the emperor, only the most senior officials were allowed to wear nine dragons on their robes — and then only with the robe completely covered with surcoats. Lower-ranking officials had eight or five dragons on their robes, again covered with surcoats; even the emperor himself wore his dragon robe with one of its nine dragons hidden from view. There are  many places in China with the phrase "Nine Dragons" in their name, the most famous being Kowloon (in Cantonese) in Hong Kong. The part of the Mekong in Vietnam is known as "Cửu Long", with the same meaning.
