Pukawang, the riverside village where buckwheat is sown

Pukawang means "the riverside village where buckwheat is sown" in the Dulong language. There is a river formed by snowmelt next to Kongdang Village in Dulongjiang County. On the sunny side, the river is blue. On the shady side, the river is emerald green. The same river changes from blue to green under the sunlight. The stones on the river beach are like jade. Listening to the sound of the water, you will feel at peace. Who has ever seen such pure blue?
