Chinese in senior high school: appreciation of ancient poetry. What does the image of "East Wind" generally mean?

Dongfeng is the messenger of spring. "White Tiger and Five Elements" says: When the East moves, everything moves. Therefore, "East" brings people a bright and warm direction, with the characteristics of light, warmth and rebirth, symbolizing the beginning of a year and the spring when everything recovers. The east wind mentioned in classical poetry is spring breeze. In the theory of five elements, the east belongs to wood, and the east wind blows, bringing spring and a prosperous season for everything.
