2. When Wu Han was in Tsinghua, he wanted to buy a Chronicle of Ming Dynasty. Because he had no money, he rushed to write a story about The Riverside Scene at Qingming Festival and Jin Ping Mei, and bought this book for 10 yuan. However, he is not satisfied with his article. In a letter to his teacher, he said, "I drafted it in a hurry during the summer vacation, but I don't want to publish it." Because I want to buy a Chronicle of Ming History, I can't make money at the moment, so I can only send it to our weekly magazine. If I get 10 yuan, I can probably buy one.

In the second year, he wrote a supplementary explanation for this article, which further corrected and filled the blank of this article and made his views tend to be perfect.
