Qing Yu Ji

Thousands of tree branches have fallen, and the ground is filled with sorrow. People on land and sea rise to the sky in sorrow. Qingyu said to Yuxuan, tree, tree, the branches will be green again in spring: Summer is full of vitality; Autumn comes and goes yellow, and the ground is desolate; When winter comes, snow covers the ground, and it's time for me to go back.
