Chiaotzu (餃子, Chaozu) is a white-skinned, red-cheeked little Human. He is the constant companion and best friend of Tien Shinhan and one of Master Shen’s students.
Chiaotzu is a human who possesses a few different traits than most, such as plain white skin and red cheeks. Like Krillin, Chiaotzu does not have a visible nose and is quite short in height. Chiaotzu has a single, wiry hair on his head, only seen after he removes his hat. His outfit throughout the majority of the series consists of the entire Crane School uniform. By the second half of theVegeta Saga, however, he ditches the robe for a white tanktop. In the Majin Buu Saga, like Tien Shinhan, Chiaotzu wears a blue Hanfu (Han Chinese-style) robe with a white cloak and pants, and though he wears a Mongolian-style hat in the manga, he keeps the Crane School cap in the anime.
Chiaotzu is based on Jiang Shi (Chinese vampires). The similarities are displayed in both his appearance and also when Chiaotzu performs some of his attacks. Jiang Shi are described as having white skin, red cheeks and wearing an outfit from the Qing Dynasty. These ghosts cannot walk (only hop), and they always keep their arms stretched out in front of them. These qualities are all referenced in Chiaotzu to some extent: when first encountered, Chiaotzu flies more often than walks and his attacks are executed by stretching his arms. Chiaotzu’s outfit also resembles a Qing one.
Another possibility is that Chiaotzu was inspired by Nezha from Journey to the West, the novel Akira Toriyama used as a prototype for his own work when he began creating the Dragon Ball manga series. Nezha is usually depicted as a baby with a totally white body, much like Chiaotzu. Nezha is an opponent of Sun Wukong (who inspired Goku) and one of his allies is Erlang Shen, a god depicted with three eyes. This makes Chiaotzu and Tien a fitting pair, being similar in appearance to Nezha and Erlang respectively.
