I thought that the Quili River was the branch of Rao River, but I took a long time to get here by bus. I haven't got off the bus yet, and I was deeply attracted by his blue. Maybe it's because the sky is too beautiful or because the weather is too good. The bright sun spilled on the river, making the river look particularly blue, and I have to admire the good air quality in the northeast, especially in Heilongjiang.
