Okay, I saw this movie when I was very young and only remember a few details. The movie was old enough that the coloring looked weird. I can’t remember clearly enough to say for sure, but I think it’s possible color was added after the movie was filmed.
The plot (as far as I can remember) is that something is happening in China that causes the main couple (who are poor) to flee for their lives. As they are fleeing, they run through this area where wealthy people lived and the wife finds a bag of expensive jewels. With it, they are able to become wealthy. But once they are wealthy, the man forgets how much he loved his wife and marries a second wife who is younger. Eventually he remembers how important his first wife is to him.
Additional detail: I believe they use the jewels to buy a rice field.
