"The stream is full of mountains." From the Song Dynasty's "Three Roads in the Road", "Plums are yellow and sunny, but the stream is full of mountains." The green shade does not reduce the road, but it adds four or five sounds of orioles. " When plums are ripe, it is sunny and fine every day. Take a boat to the end of the stream and then take the mountain path. The ancient trees on the mountain road are green, which is not inferior to the scenery on the water road. There are a few orioles singing in the deep forest, which adds some fun.
