"A hundred flowers are blooming" comes from "Qingcheng Hermit" by Zhao Bi in Ming Dynasty: "It's mid-spring, and a hundred flowers are blooming."
For example, a small courtyard is a scene of a hundred flowers blooming, and the small building in the south of the Yangtze River with red bricks and green tiles seems to be spring back to the earth, full of spring.
Speaking of the word "flowers bloom", the first thing that comes to mind must be spring, that is, a flowering season, when everything recovers and a hundred flowers blossom. For example, the peach blossom in China's traditional culture is an important sustenance for China people to place all kinds of beautiful feelings in spring.
