/kloc-one day in 0/930, Liu Wendian, a professor from Tsinghua University, went to Peking University Library to borrow reference books for sorting out ancient books. As soon as he entered the library, he handed the book list to a young librarian. I saw that the books listed on the list are precious ancient books, and at the end, it was marked "For proofreading books, please let the curator check them out". The administrator dared not neglect, so he asked the curator. The curator was worried that these ancient books would be lost, so he asked the librarian to find an excuse to refuse Liu Wendian's request. Helpless, Liu Wendian had to leave bitterly.
At this time, the administrator suddenly thought of something, quickly grabbed a piece of waste paper and wrote down the list of books just now from memory. After that, he looked for books on the list to study as soon as he had time, and he benefited a lot. The young administrator, Jin Kemu, only had a primary school education, and later became a famous scholar by self-study.
Many years later, Jin Kemu mentioned this to Liu Wendian and thanked him: "At that time, I didn't know what to read without the guidance of my teacher. It was your book list that showed me the way. " Liu Wendian asked inexplicably, "How do you know the books on my list are worth reading?" Jin Kemu smiled and said, "You are a great scholar. If you are willing to make a special trip for these books, it is certainly worth reading. "
