In Wang Wei's Farewell to Yuan Er's Ambassador Anxi, "Weicheng is light in the rain and dusty, and the green willows in the guest house are new in color", which shows a warm and fresh spring scenery, but the poet is uneasy and disappointed because of his farewell to his old friend and his experience. It can be seen that writing sadness in a happy scene can better highlight the sadness of the poet's farewell to his friends and the concern and sympathy of his friends for their lives after "going out for no reason."
