There is a road in China. It rains heavily for half a year and is covered with ice and snow for half a year. The scenery is beautiful but it is extremely difficult and dangerous. Because of its complex geological conditions, it is "preferred" by natural disasters such as avalanches and mudslides. This 117-kilometer-long highway has been built for nearly 50 years. It has undergone five major repairs and countless minor repairs. It was not opened to traffic until the beginning of this year. The Medog Highway in the county is a veritable "Heavenly Road"!
