The Bayin River in Delingha is so beautiful. The blue-green river is not transparent, but there is a pure feeling, which may be unique to the plateau river. Delingha City is really clean, the greening rate is particularly high, there are parks and trees everywhere, very airy, very livable. Not a backward town in the imagination. It is much better than a small city. It is a park with small roads on both sides of the Bayin River. It is especially pleasant to stroll here and enjoy the beautiful scenery of the Bayin River. It is really difficult to see that this is a city of three kilometers above sea level. Like Delingha.
