A movie in which a man cuts a child's heart to treat a disease.

You may be talking about the film "Xi Wei" co-produced by China and Thailand. You attended the 2005 Shanghai International Film Festival, which was directed by Nyada Sudana, female directors of Thailand, and the whole film was filmed in Thailand. Starring Duan Long (Help! I like him so much! ), his lines in the whole movie are no more than ten sentences, but the characters are accurate and vivid. . . As Lan Xiaolong said, he is a remnant of the acting school.

Xi Wei is based on real events. The prototype of the hero is the famous Thai criminal Wei. In people's minds, he is a heinous "devil".

The following passage comes from Baidu: 1946. He was a soldier during World War II. He was only 19 years old (Xi Wei) and came to Thailand with a knife left by his mother, eager for a new life. Unfortunately, his life in Thailand was very hard. He was seriously ill and weak since he was a child, and lived a life of humiliation by strangers. Homesickness, coupled with despair of life, began to distort his personality, and he began to kill children one by one, filling his body with their hearts and boiled water-he also tasted such a taste in China. Finally, he was arrested and confessed his crime. 1959, Wei was sentenced to death. However, children continued to disappear and were killed.
