Tibet is due to the collision between the Indian plate and the Eurasian plate, which led to the formation of the Qinghai-Tibet Plateau. Geologically, this movement is called the Himalayan movement. The majestic momentum of the Qinghai-Tibet Plateau is the highest plateau in the world and the highest terrain step in China. It is known as the "roof of the world". The mountains in Tibet are comparatively numerous and are a sea of mountains. Like the Gula Mountains stretching north, the Himalayas stand in the south, Hengduan Mountains in the east, Kunlun Mountains in the west, Nianqing Tanggula Mountains and Gangdise Mountains in the middle.
