Who can briefly talk about the plot of Kung Fu Dream in Jackie Chan's martial arts films?

Parker (played by jaden smith), an American black boy, came to China for the first time and met Mei Ying, who plays the violin very well, but Lu Weicheng, who was born in Longteng Wushu School, led his partners to beat him many times. Once, when several people were beating Parker, Mr. Han (played by Jackie Chan, the repairman) from Parker Community saved him in time. Under his leadership, Parker reconciled with Lv Weicheng's coach (played by Yu Rongguang), told Cheng and others to stop bullying him, and promised coach Parker to participate in martial arts competitions.

Mr. Han accepted Parker as an apprentice, and gradually Parker's martial arts became more and more exquisite. During the game, Parker's mother, Mei Ying and Mei Ying's father all came to watch the game. Parker rushed into the final, but his leg was injured by the students of Longteng Wushu School in the first game of the final. However, he insisted on the competition and stood in the same ring with Lu Weicheng. Although Lu Weicheng played a bad role in it, Parker won the championship. Lu Weicheng was convinced of this, personally handed the trophy to Parker and took the Longteng school team to worship Mr. Han as a teacher.
