Dragon at the end of the world

The Chinese martial arts team went to San Francisco to perform. The martial arts champion Li Guonan (played by Jet Li) won the full house of applause, and Ayou (played by Stephen Chow) in the audience was greatly admired. Wang Wei (played by Dewei), a member of the martial arts troupe, felt that he was getting older and his future was bleak. When the martial arts troupe was boarding a plane to return to China, Wang Wei left the team to stay in the United States. Guonan tried to persuade him to stay, but he was also stranded in the United States. Wang Wei attacked a police officer when he escaped from the airport, causing Guonan to be arrested by the police and facing jail time. Introduced by his relative A Ping, Wang Wei joined the Chinese gang leader Ma Ke and his gang. At this time, Guonan took advantage of the police car to get into a car accident and struggled to escape. Guonan wanted to inquire about Wang Wei's whereabouts from Aping, but the latter died due to his involvement in a gang vendetta. Aping's sister Aling (played by Li Zhi), who came to the United States from Vietnam, has since lost her support. Wang Wei grew up in the gang and took charge of his own business, while A Ling became Ma Ke's lover in order to survive. At this time, Guonan was boarding in A You's shop to make a living and look for opportunities to return to China. Wang Wei's drugs were picked up by Ayou in the melee, and the fate of this group of Chinese people living in a foreign land was connected again...
