The cotton-padded jacket in summer is used in winter, and the cattail leaf fan in winter is used in summer. Your hospitality is to light the fire after I get cold. This sentence is easy to understand, cotton-padded jacket is a treasure in winter, and in sweaty summer, it will definitely be at the bottom of the box; Pufan, I can't wait to get my hands off me in summer. In the cold winter, I naturally don't want to touch it. Using these two things to describe redundancy is really appropriate and vivid. No wonder so many people use it as a signature to express their feelings.

In fact, winter fans are associated with redundancy, which has existed since ancient times. Everyone is familiar with the poem "The bright moon is in the sky, brightening the whole of heaven". It is a famous sentence by Zhang Jiuling, a great poet in the Tang Dynasty. Zhang Jiuling was a poet in the Tang Dynasty and a prime minister in the Xuanzong period. At first, Emperor Xuanzong of the Tang Dynasty admired and relied heavily on Zhang Jiuling, but later they often disagreed, and as time passed, they became less harmonious.

On one occasion, Emperor Xuanzong of the Tang Dynasty gave Zhang Jiuling a white feather fan. When Zhang Jiuling looked at the fan, his heart began to churn. When it was cold, the emperor gave me a fan. Doesn't that mean I'm a useless fan in the cold?
