The reeds in the "reed sea" are overgrown, the water birds fly, the clear stream is blue, the green swaying green, the empty row, and the scenery of the country is good. In the "reed sea", the reeds are swung, a green onion, the breeze is coming, and the green waves are undulating. The sound of the snoring, euphemistic and lyrical, makes people feel relaxed and happy.
