"Car No. 3. This way, Please!" "Please watch your steps, don't get close to the yellow line." Whenever there is a train entering or leaving the Nyingchi Station, Norbu, a passenger clerk, can always be seen on the platform serving passengers.

Norbu, 36, is of the Lhoba ethnicity. He was born in Mailing County, Nyingchi City, Tibet Autonomous Region. In 2006, he became the first batch of local railway workers on the Qinghai-Tibet Railway.

When he heard the news of the opening and operation of the Lhasa-Nyingchi Railway, Norbu submitted two applications successively and came back to Nyingchi to work in passenger service. He knows that many people in his hometown travel by train for the first time and may not understand the carriage number and seat number on the ticket. Therefore, to serve them requires more patience and care.
