Call of the Home Village.

A 20-year old young man who has been brought up by a foster mother in the countryside has fallen in love with another foster child in the same "family" and the two have decided to get married. Just after this decision, the young man's real mother contacts him and asks him to come and stay with her and his father (she is a high-ranking Party official). She is against his marriage but her husband is not. In the end, the young man decides to marry at the home of his real parents, and when his foster mother shows up, his real mother treats her like dirt - it turns out that the foster mother was a concubine for awhile. Before things deteriorate any further, the husband has some news for his wife that helps her to see the foster mother in a different light.
