What are the starting and ending points of the Hu-Nie line?

The Hu-Nie line (National Road 3 18) starts from People's Square in Huangpu District, Shanghai, and ends at the Sino-Nepalese Friendship Bridge in nyalam county, Shigatse, with a total length of 5,476 kilometers. The administrative regions above the prefecture level are mainly Shanghai, Suzhou, Huzhou, Xuancheng, Wuhu, Chizhou, Anqing, Huanggang, Wuhan, Jingzhou, Yichang, Enshi, Chongqing, Dazhou, Guang 'an, Nanchong, Suining, Ziyang, Chengdu, Ya 'an, Ganzi, Qamdo, Linzhi, Lhasa and Shigatse.

Because the 3 18 national highway spans the east, middle and west of China, including plains, hills, basins, mountains and plateaus, including the water town culture of Jiangsu and Zhejiang, the Tianfu basin culture and the Tibetan culture landscape, it has the strange, dangerous, unique, beautiful, heroic and strong landscape all the way from Chengdu Plain to Qinghai-Tibet Plateau, and was awarded the title of 16 by China National Geographic magazine.

The most beautiful road of National Highway 3 18 is caught in a garbage dilemma, and the speed of tourists throwing it far exceeds the speed of cleaning.

The garbage problem of national highway 3 18 also makes the management department very headache, and it is too late to clean it up. Kazila Mountain is located in Litang County and Yajiang County, Sichuan Province, and the observation deck of Kazila Mountain is managed by Litang County Cultural Tourism Bureau. A staff member of Litang County Cultural Tourism Bureau told the reporter of Beiqing Daily that May 1 day,1day and July 8 are the tourist peak seasons of Kazila Mountain every year, with large passenger flow and the most serious littering by tourists.

According to this staff member, during the tourist season every year, the Tourism Bureau organizes cleaning twice a week. Starting from the urban area of Litang County, it takes more than an hour to drive along the road to pick up garbage and drive to Xiongzongka Tunnel. Only on the observation deck of Mount Kazra, they can clear three or four bags of garbage at a time during the peak season.

Even so, tourists can throw rubbish much faster than they can pick it up. The staff said that once they just cleaned up the garbage on Tuesday, and when they went back on Friday morning, it seemed that they had never cleaned it. "Sometimes we are cleaning, tourists throw garbage out of the window, and the trash can is nearby and we don't want to throw it down."
