What they say

Gui Zhijing, an official with the safety and quality supervision and management department under the Ministry of Transport and deputy Party secretary of Sertar county in the Tibetan autonomous prefecture of Garze, Sichuan province

Sertar county, where I have been working since 2018, sits at the junction of Sichuan and Qinghai provinces, with an average elevation of over 4,100 meters. The oxygen content there is only 65 percent of that in Beijing. Due to its remote location, Sertar remained one of the country's slowpokes in the transportation sector. With the development of transportation infrastructure on the fast track over the years, yak breeding bases, plateau vegetable planting bases and handmade soap factories have sprung up, offering many jobs to local farmers to help them eradicate poverty. Because of the improved roads, people's lives are getting better and better.
