On the way to Namu, passing the observation deck of Nianqing Tanggula Mountain, you can overlook the snow peaks here, the yak in the pasture, the railway line in the distance, occasionally there are green trains passing by, the sky and the ground are far away, and there is no sight. It is indeed a very shocking scene. The altitude here is already relatively high, people from the plain will be a little short and weak, see the beauty do not get too excited.
