I'm looking for a Chinese movie....?

This movie is about a family in China. It is during the time Mao was in office. They are always talking about how great China will be if everyone works together and contributes. The whole village always eats together under the communist regime. This family has a small son that gets killed while sleeping behind a wall and it collapses on him. There is one scene in a hospital where they feed this man some rolls and then he drinks too much water. The rolls expand in his stomach and it causes problems. The mother always takes a little box of dumplings to the boy's grave and she blames the father for everything all the time. These are just random scenes from the movie. There is also a little story or fable that they tell a couple of times during the movie that is directly related to the title. I'm hoping someone will recognize it and give me the title. I've been looking for this movie for 3 years. Thanks!
