Ideologically, Dong Zhongshu's suggestion of "ousting a hundred schools of thought and respecting the Six Classics alone" was adopted. Liu Che was good at poetry and fu, and attached importance to cultural construction. For the first time in history, the government ordered the nationwide collection of books, which opened the way for book donation. The strategy of building a library is to put officials in charge of books, and all kinds of books are widely filled in the secret room. For decades, history has called "books accumulate like mountains". [86-87] At that time, the government library had all the books of Taichang, Taishi and Doctor, and there were Yan Ge, Guangnei and Secret Room [88] in the palace with 33,090 books. The royal family and government have an unprecedented wealth of books. This is the first national library with clear records in the history of China.
