In the two hundred years since SikuQuanShu was written, China has experienced turbulence, and SikuQuanShu has also experienced vicissitudes, and many manuscripts were destroyed by war. Its China source pavilion was captured by the British and French allied forces in 1860, and the Yuanmingyuan was burned when it was burned, while the Wenzong and Wen Hui pavilions were destroyed in the Taiping Heavenly Kingdom Movement. Hangzhou Wenlange Library Building collapsed 186 1 when Taiping Army captured Hangzhou for the second time, and Sikuquanshu was scattered among the people. After cleaning, sorting and supplementing by library collector Ding Brothers, a quarter of the original books were rescued and stored in the restored Wenlan Pavilion on 188 1. During the Republic of China, the Wen Lan Pavilion was renovated again on a large scale, and most of its contents have been restored. Therefore, there are only three and a half sets of Sikuquanshu. Its Chinese library was originally hidden in the Forbidden City in Beijing, then transferred to Taiwan Province Province through Shanghai-Nanjing, and now it is hidden in the National Palace Museum in Taipei (which is also a relatively well-preserved set). Wen sui ge Ben 1922 was almost sold to the Japanese, and is now in the library of Gansu province. In recent years, Gansu and Liaoning provinces have been unable to reach an agreement on whether to return this book to Shenyang. On 1950, the Jinwen Museum in the Summer Resort was handed over to the National Library of China by order of the China Municipal Government, which is the only preserved version of the original book. The incomplete collection of Wen Lan is in Zhejiang Library.
