One of them, Don't Move Big, is about winter. What is the basis?

One of the reasons why Don't Move Big was written in winter is that there is a saying that the north wind blows wild geese and snow.

A poem describing winter-"Don't Move Big" thousands of miles away, the sun is shining in Huang Yun, and the north wind is blowing geese and snow. A gentleman is poor, who wants to meet today without paying for drinks?
