What poem does Longing for Love come from?

In spring, the West Lake sends a thank-you song to Cao Cao.

Ouyang xiu returned to the west lake in spring, and the spring water was green. If the flowers rot, the east wind falls like a nest. Joining the army, spring thoughts are like clouds, and white hair is full of poems. Know a bottle of wine from a distant lake, and you will remember the people in Wan Li, the ends of the earth. Wan Li's longing for spring is still deep, and he is suddenly frightened by spring. It's snowing outside, Qian Shan is green, and the riverside in February is in full bloom. Teenagers put wine in spring, and white in spring today. The state of foreign land is different from that of people, only the east wind knows the old.
