Four. Identification of Tibetan Buddhist cultural relics I am familiar with the overall situation of Tibetan Buddhist cultural relics in China and have accumulated rich practical experience in cultural relics identification. 1996, as a member of the National Cultural Heritage Administration expert group, participated in the first-class cultural relics identification in Xinjiang, Gansu, Ningxia and Qinghai in northwest China, and was responsible for the identification of Buddhist cultural relics. I went to Tibet many times to identify cultural relics and understand the collection of cultural relics in Tibet. Appointed by National Cultural Heritage Administration in 2002, together with Mr. Zhu Jiajin and Mr. Shi Shuqing, the cultural relics unearthed in the underground palace of Hangzhou Leifeng Pagoda were identified and graded. In 2003, appointed by the Ministry of Public Security and National Cultural Heritage Administration, he went to Hong Kong and Macao to identify and recover the stolen Chengde cultural relics, which contributed to the recovery of major national cultural relics losses.
