This book is written by Han Yuzhi’s family motto: “It’s easy for a big man to get married, and it’s not difficult for a gentleman to aspire. It’s natural and graceful to step back, and how easy it is to make three points. Tolerate a few words of worry-free and comfortable, and be happy for a moment. I am not surprised. Someone asked me about the worldly affairs. He waved his hand and said that he did not know. I don’t see the poor, the long and the rich.
