How does the poem Cold Food express the east wind? What's good about saying that Spring City flies everywhere?

The wind is invisible, and its existence can only be indirectly perceived through the flight of flowers and the inclination of willows. A word "oblique" also indirectly wrote the wind.

The phrase "Spring City" has a lofty foothold, a broad vision and a panoramic view of the whole city. Highly concentrated and gorgeous; The double negation style of "flowers flying everywhere" greatly strengthened the tone of affirmative sentences, and effectively set off the grand occasion that the whole city has been immersed in Fuchun.
