Hou, the master of crosstalk language, only attended primary school for three years. Because he is diligent and studious, his artistic level has reached a perfect level and he has become a famous language expert. On one occasion, in order to buy the joke book "The Waves" of Amin Dynasty that he wanted to buy, he went to all the second-hand book stalls in Beijing but failed to buy it. Later, he learned that Beijing Library had this book, so he decided to copy it back. In winter, he braved the heavy wind and snow and ran to the library to copy books for 18 days in a row. A book of more than 100,000 words was finally copied by him.

2. Zhang Guanghou eats books.

Mathematician Zhang Guanghou once saw a paper about deficient value, and thought it was very useful for his research work, so he read it again and again. This paper has more than 20 pages, and he has read it repeatedly for more than half a year. Because of repeated groping, clear black marks were left on the white pages. His wife joked with him that it was not reading, but eating books.
