My daughter-in-law is ill and wants to take her to see a doctor in Golmud. It's great now. In the past, we all had to walk for three days, but now we can arrive in a few hours. The train really brought us good news. At Tuotuohe Station, Zhuo Ri, who took his wife to see a doctor in Golmud, said generally, but he still remembered the hardships of reversing. Tanggula Mountain City, with an average elevation of more than 4,700 meters, is the first town at the source of the Yangtze River, with an area of 47,540.08 square kilometers. It is a pure animal husbandry town with Tibetans as the main body and a vast territory and sparsely populated. Most villagers in the town have never taken a train, and the income of farmers and herdsmen is very low. In the past, people in Tang Zhen had to rely on the Qinghai-Tibet Highway, which made it extremely inconvenient to see a doctor and travel. Since the official opening of the 1 Qinghai-Tibet Railway in July, 2006, everyone has been happy to call this railway the "rich line" for the villagers, making it very convenient for people in Tang Zhen to travel. At the same time, people no longer regard the development of animal husbandry as the only means of making a living, but turn their attention to how to make a fortune by railways and try their best to use the role of the Qinghai-Tibet Railway to drive the economic development of cities and towns. Zhao, secretary of Tang Zhen, told reporters: "Since the opening of the Qinghai-Tibet Railway, it has played a great role in the economic development of the whole town. As for the transfer of surplus labor, it has transferred 12 people to Tang Zhen, increasing the income by 250,000 yuan. At the same time, it has also brought great benefits to the construction of our ecological town and brought great aspects to the travel of herders.
