In addition to describing the arrival of spring, this allusion can also be used to describe the development and growth of something or someone in a certain period. For example, we can say that a company grows rapidly under the south wind of the market economy, or that someone has gained more development opportunities in a certain environment, just like the south wind blows green branches. In a word, the allusion of "the south wind blows green branches" is a very beautiful metaphor, which shows the beauty and vitality of nature and can also be used to describe the development and progress of human society.
