What does it mean to enter Tibet? What is the explanation?

(1) Compile a series of existing Buddhist classics, which is called Tibet. That is, compiling the Chinese version of Indian Buddhist scriptures and descriptions written by practitioners in China and Japan. Since the end of the Eastern Jin Dynasty, Daoan has comprehensively sorted out the existing contemporary classics and compiled a comprehensive catalogue of classics. By the time of the Southern Qi Dynasty, monks had written the Sanzang Collection, and compiled a catalogue of the translated classics in the Eastern Jin Dynasty, Liu Song Dynasty and the Southern Qi Dynasty. The above two are just the catalogues before the compilation of Dazang, and there is no difference between big and small multiplication or Confucian classics. The Tripitaka was signed in the 17th year of Tian Liang (5 18), and Chang Bao of Zhuang Yan Temple and others wrote four volumes of Liang Shizhong Jing. In the middle of Wei Yongxi's reign (532 ~ 533), Li Kuo wrote a volume of Wei Shizhong's classics. In the middle period of Gao Qi Wuping (570 ~ 575), a volume of Qi Shizhong Jing was compiled according to law.
