It's Two-faced Man, starring Zhang Chenguang and Song Gangling. The hero is having an affair, and he doesn't like his ugly wife. Something happened when the couple went out. It happened that the woman was saved by the doctor, and she was given plastic surgery, which made her look beautiful and completely changed into another person, so no one recognized her and thought she was dead. Later, she simply changed her name and surname and lived a new life. It seems that she is still pursuing her husband for revenge in her career, but she still can't let go of her daughter and father. I can't remember what happened later. Anyway, what is certain is that the doctor who operated on her fell in love with her, and her husband later wanted to get back together with her when he knew her identity.
