Not included. The shade does not reduce the road, but adds four or five orioles. This poem is about the quiet scenery in early summer and the poet's relaxed and happy mood when walking in the mountains, without allusions. The shade does not reduce the road, adding four or five orioles, which comes from the once famous "Middle Road and Three Roads" in the Song Dynasty, meaning that the ancient trees on the mountain road are green and not inferior to the scenery on the water road. There were a few orioles singing in the depths of the forest, which added a bit of interest.
