This year marks the 20th anniversary of the full operation of the Qinghai-Xizang Railway. As the Spring Festival approaches, let us embark on this legendary "Sky Road" and explore stories of perseverance and human endeavor.

Train Z8991 departs from Xining in Qinghai Province, passes through Ge'ermu, Bu Dong Quan, Tuo Tuo He, Yanshiping, Amdo, and Nagqu, and finally arrives in Lhasa, Xizang. Recently, our reporters boarded this train and captured the unforgettable moments along the journey.
