An old 18+ erotic Asian movie

Greetings everyone. I would like to find an Asian (most likely Chinese) erotic comedy movie. I think it’s from the late 80’s or 90’s. I can only remember the last scene, in which a woman and her boyfriend or something were gambling at a casino. The woman lost her top after wagering all of her clothing. She casually removed her top in front of everyone and carried on with the game. The movie came to a close when she won large and exited the casino topless with her boyfriend. I think there was another scene in the middle of the movie where she walked casually topless outdoors too. That’s all I can remember. I hope someone can help me with this. Thank you in advance.
