In the Spring Festival Evening, Cui Tu appreciated the first couplet "Flowering flowers and thanking two heartless people for sending the east wind in the process of spring"

Cui Tu's appreciation of the first couplet "Flowing flowers and thanking two heartless people for sending the east wind in the process of spring" depicts what scene? What's the role? Write a scene to describe a late spring scene: spring water flows far away, spring flowers wither, and running water falls on spring leaves. Writing feelings with scenery and containing feelings in scenery express the poet's sigh over the fleeting spring and ruthless years. I personified Dongfeng, but it wasn't the spring breeze that sent me back to my hometown, but I sent me home in a foreign land. The word "send" expresses the poet's sadness. Falling red all over the ground, the lingering spring scenery of catkins all over the sky touched the poet's homesickness (sadness)
