What's so funny about Su Daqiang played by Dahongni in Everything is Fine?

When I was old, I thought I had met an unattainable object and wanted to marry my nanny Cai Cai. To say that Su Daqiang's feelings are also pitiful, his love path is a miserable word. When I was young, I married Zhao Meilan, thinking that I had met love. As a result, I suffered for most of my life and was almost put on a green hat. Now finally ushered in the sunset love in life, but I was opposed by the whole family, saying that the little babysitter wanted his house. Well, it was the funniest moment in Su Daqiang's whole play, and he was forced to sell his house to find a nanny.
