I want to know the name of a movie. It's probably about a boy named Derek Parker who immigrated to China.

Adapted from the film remake of 1984, the American film Karate Kid 1984 (Longwei Kid) jaden smith will play Parker, a child who was bullied before learning Kung Fu, Jackie Chan will play his Kung Fu master, and Tara's Kung Fu Dream movie poster (6) Ji P Hansen will play Parker's mother. Mainland middle school student Han Wenwen plays Parker's good friend Mei Ying; Mainland actor Wang Zhenwei plays Lu Weicheng, the bully in the school; Jin Shihao, a famous mainland child star, plays Jackie Chan's son; Yu Rongguang plays teacher Lu Weicheng. Parker came to China for the first time and got to know the United States and Britain, who played the violin very well. However, Lu Weicheng, who was born in Longteng Martial Arts School, led his partners to beat him many times. Once, when Lu Weicheng was beating Parker, Mr. Han (played by Jackie Chan, the repairman) from Parker Community came to the rescue in time. Under his leadership, Parker went to make peace with Lu Weicheng's coach, told Cheng Gang not to bully him again, and promised Coach Parker to participate in a martial arts competition. Mr. Han accepted Parker as an apprentice, and gradually Parker's martial arts became more and more refined. During the game, Parker's mother, Meiying and Meiying's father all came to watch the game. Parker rushed into the final, but in the first game of the final, his leg was injured by the students of Longteng Martial Arts School. But he insisted on the game and stood in the same ring as Lu Weicheng. Although Lu Weicheng played a bad role in it, Parker won the championship. Lu Weicheng was convinced, personally handed the trophy to Parker, and took the Longteng school team to worship Mr. Han as a teacher.
