China has the capability to build an expressway linking up Tibet autonomous region and Qinghai province if major technical barriers are overcome.
"To build a road in my hometown is my life long dream," said Sina Dingdru, general manager of Bara Gedzong Tourism Development Co in Shangri-La county of Yunnan province.
Passenger transport service started Saturday on the newly opened Lhasa-Xigaze railway, the second rail line in southwest China's Tibet Autonomous Region.
A second railway line in Southwest China's Tibet autonomous region, an extension of the Qinghai-Tibet railway, the world's highest, was officially put into use on Friday.
A comprehensive transportation system that includes highways, airlines, railways and pipelines is gradually improving. Completion of the Qinghai-Tibetan railway in 2006 ended Tibetan's history without railways.
Like Tsering Degyi, many of the maintenance workers on the Qinghai-Tibet Highway have left their children in the care of their grandparents. However, the situation is much better than it once was.
