Hi, I'm looking for an old Chinese movie but i'm having trouble identifying the title. I believe the actress was Tien Ni. It was filmed probably in the early 70's. It starts out with a man leaving his wife and 2 kids on a ship to go to America to complete his education. As her husband leaves she's obligated to find a source of income so she works in a bar as a call girl. Her family (mother and sister) eventually find out and disapproves and her kids are ashamed. Her husband then returns and she finds out her husband met someone else in America and he is now engaged to her. In the end she ends up dying and the ending scene is the father and the 2 kids at her grave. Can someone help me identify this movie? Heres a picture of it from a Cambodian soundtrack version of it as it was shown in Cambodia and very popular at the time.
