What is the name of a sketch by Pan Changjiang and Gong Hanlin about how to get rich in rural areas?

This sketch is an early work of Pan Changjiang and Gong Hanlin. It tells the story of a brother-in-law from the countryside played by Pan Changjiang who went to the city to find his brother-in-law played by Gong Hanlin. This brother-in-law is a newspaper reporter, and he is afraid that his brother-in-law from the countryside will ask him for something at the same time. The plot and dialogue of the sketch are very funny. I remember a jingle: "What if the countryside wants to be rich and have fewer children to grow garlic?" "How can the countryside not have fewer children?"
