Peking University Classical Literature does not offer the major of ancient books restoration, but a considerable number of masters or even doctors who graduated from Peking University Classical Literature eventually entered the ancient books department of the National Library. Have the opportunity to study and engage in the restoration of ancient books. I don't know if you are an undergraduate or a master. If you are interested in this line, you can look at the new edition of "Illustration of China Ancient Books Restoration and Mounting Techniques" by Zhonghua Book Company, which contains a large number of color pictures. In addition, there is a master's degree in the collation and protection of ancient books offered by the Institute of Ancient Books of Wuhan University, so you can pay attention to it.
You ask, is China's classical literature in Peking University good? Well, it depends on what you ask. Ask the teacher, there are more teachers than students here, and the teaching and research section and the National Committee for the Arrangement of Ancient Books are in the same office area, which should be said to be the best. When asked about their employment prospects, they usually go to universities, libraries or publishing houses. Most of them do academic work, and they may make money, but I don't know them.
