Busy Flying a Kite in the East Wind is from Village Residence written by Gao Ding, a poet in Qing Dynasty. In network language, it means to seize the opportunity to do something and follow the trend.
The original text of "Village Residence" is: the grass grows in February, and the willows on the embankment are drunk with spring smoke. The children came back from school early, so they were busy flying kites in the east wind. The poem describes the spring scene when spring comes and everything recovers.
