Because she looks like Stephen Chow when she was a child, Jiao Xu, a 9-year-old girl from Ningbo at that time, became the lucky one among thousands of people. She cut her hair short and became Xiao Di, the son of Stephen Chow in Changjiang No.7. Of course, we prefer to call her "Little Star". It is said that Stephen Chow interviewed nearly a thousand boys and couldn't find a suitable actor. Three days before shooting, it was "burning eyebrows". When Stephen Chow saw the recommended Jiao Xu, she recognized her at a glance, and decided to play her son in a "cross-dressing" way, which even surpassed Stephen Chow himself in the film.

Although Jiao Xu is young, he is an old student of Ningbo Seven-color Flower Art Troupe. When she was 6 years old, she was admitted to Qicai Flower, the youngest child at that time, and soon stood out and won many awards. Interestingly, she was called one of the freaks in the school by the seven-color flower teacher-a clever elf.

Because Jiao Xu is cute and sensible, and she can bear hardships-it is said that she is the earliest one in the whole crew every day. During the filming of "Changjiang No.7", Stephen Chow became more and more attached to Xu Jiao, and later simply recognized her as a "goddaughter". And Master Xing are also very close, and they often beat about the bush on the set. Stephen Chow, who has always given people a harsh and even harsh impression, has always been more tolerant of Jiao Xu. According to media reports, Jiao Xu NG made many moves, but Stephen Chow didn't lose his temper at all, and he personally squeezed into the middle of the young actors to demonstrate, "occasionally showing a rare smile".

Stephen Chow publicly praised Jiao Xu for many times, calling him "a rare genius child star in a hundred years". So Xinghui Company signed an eight-year contract with Jiao Xu, and Jiao Xu became the youngest among the "star girls". In order not to bury Jiao Xu's talent, Stephen Chow also plans to apply for a "gifted student" program for her to study in Hong Kong, with full tuition and living expenses.
