The east wind blows thousands of trees and the stars fall like rain. What season is it?

Thousands of trees bloom at night in the east, and the stars fall like rain. It is winter, because this poem comes from Xin Qiji's Jade Case in the Song Dynasty, which refers to the Lantern Festival. The Lantern Festival is on the fifteenth day of the first month, so it is winter.

The translation of this poem is that when the east wind blows, countless lanterns shake, as if to push away thousands of trees, fireworks are chaotic, falling down, and the stars in the sky are blown down like a shower of stars.
