The film is based on the Hollywood 1984 film of the same name. 12-year-old Drey Parker (Jaden Smith) accompanied his mother (Taraghi Smith) Taraji P. Henson moved from Detroit to Beijing, China, and met Mei Ying (played by Han Wenwen), a Chinese girl who plays the violin at the same school. In a fight, the disadvantaged Derui is rescued by the apartment administrator Lao Han (played by Jackie Chan), but offends Cheng's martial arts teacher, Master Li (played by Yu Rongguang). Lao Han and Master Li agreed that the apprentices would compete in the martial arts competition. Since then, Derui began to learn Chinese kung fu under Lao Han, from fist and foot practice to personality cultivation, little by little to understand the true meaning of martial arts and life, and at the same time established a deep friendship with Lao Han. But will Derverium, who has only been training for a short time, be able to defeat Cheng in the brutal martial arts competition and achieve the final victory?
