Reasons:
1. Zhou Yongnian advocated the theory of Confucianism and Tibetan again from Cao Xuequan in the late Ming Dynasty, and advocated the collection of Confucian books, which stood firm with Buddhism and Taoism.
2. Qianlong sent a letter to the provincial governor for a suicide note, which was sent to the capital.
3. Zhu Yun and Wang Yingcai invited the school to run Yongle Dadian and compile lost books. But in fact, it is the need of the development of academic culture to the summary period and the joint efforts of academics and politics.
In November of the thirty-seventh year of Qianlong (1772), Zhu Yun, an Anhui scholar, put forward the problem of compiling Yongle Dadian, which was recognized by Emperor Qianlong, and then he ordered the compilation of the lost books with "all the books collected by the provinces and engraved by all the officials in Wuying Hall", which was called Sikuquanshu.
in this way, the compilation of Yongle Dadian led to the huge project of compiling Sikuquanshu, which became the direct reason for compiling Sikuquanshu. Extended information
Since Sikuquanshu has to include all the ancient books and records before Qianlong, it is duty-bound to summarize the traditional scholarship, because the traditional bibliography just arranges and arranges the books and records according to a certain system, and then reflects the academic development history through the literature and books themselves, classification, cataloging and sequencing.
Therefore, it has become an important task for the compilers of Sikuquanshu to arrange ancient books and summarize and judge traditional scholarship, and the catalogue of Sikuquanshu came into being.
In the two hundred years since the completion of Sikuquanshu, many manuscripts were destroyed in the war. In 186, the English and French allied forces captured Beijing and burned it when the Yuanmingyuan was burned. Wenzong and Wenhui Pavilion were destroyed during the Taiping Heavenly Kingdom Movement.
The Wenlange Library in Hangzhou collapsed in 1861 when the Taiping Army captured Hangzhou for the second time, and the Si Ku Quan Shu was scattered among the people. After that, it was collected, sorted out and copied by the Ding brothers, and only a quarter of the original book was saved. Wenlan Pavilion was copied twice in the Republic of China.
In the third year of the Republic of China (1914), with the support of Qian Xun, the first director of Hangzhou Library, Xu Zhongsun, the second brother of Xu Xilin, and his students made up copies at their own expense, which lasted for seven years, and was known as "Yi Mao made up copies".
In the 12th year of the Republic of China (1923), Zhang Zongxiang, then the director of education in Zhejiang Province, was very moved when he learned of Xu Zhongsun's and Du Fu's righteous actions, but he knew that the amount of "mending" was huge, and it was difficult for a few people to complete it, so the government must take the lead.
under his attention, the number of people who make up copies increased to more than 1, and all the expenses were raised by Zhejiang people. Xu Zhongsun was appointed as the general school and blocked Fue as the supervisor for two years, which was known as "making up copies in Guihai". At the beginning of liberation, the portraits of Xu Zhongsun and Du Fu-e were hung in Wenlan Pavilion, Hangzhou, to commemorate them.
