Ask for two old movies from the 1980s.

I have seen the second film. It was really shot in the 1980s, with a little comedy. The hero is a factory worker. In the film, he seems keen to catch thieves and cooperate with the police station to crack down on rogue gangs of bad forces. He also saved a girl with a problem. The bad gang leader in the movie seems to be called Iron Dragon. The protagonist and his wife seem to play a lot of jokes in the whole movie. There are many enthusiastic citizens in the anti-piracy volunteer team, and it seems that there are also members of the Wushu team involved. The hero once gave money to a little beggar in the street. At the end of the film, he was kidnapped by a gang of hooligans and sent to his lair. In a warehouse, the bad guys want to get rid of him. The little beggar was there, too. He lied to each other that he practiced Qigong. The bad guys don't believe me. Ask him to demonstrate. The little beggar volunteered to sit opposite him in order to save him. The hero imitated the appearance of practicing qigong, and his head was angry on the wall. As soon as he pushed it out, the little beggar fell to the ground. The bad guy didn't believe it. Another man sat opposite him and another man fell to the ground. Bad guys have to believe it. At the critical moment, the police arrived, left him behind and wiped out the evil gang. The hero finally asked the man why he pretended to fall to the ground, and he replied that he wanted to end the past and start over.

I really don't remember the name, but I remember so much about the plot. I hope it helps you.
