What do you mean by plum blossom before slight cold?

It means that the slight cold season has arrived.

This sentence comes from Winter written by Zhu, a poetess in the Song Dynasty.

Ling Huang should use the law to promote the wind, and the yin will rise while the yang will rise, so as to relax.

Sunflower shadows will move to the sun, and plum blossoms will bloom before the slight cold.

According to the law, the yellow bell has reached November, the yin lurks, the yang rises, and the gentle qi gradually returns.

Winter solstice is as long as the sun, the shadow of sunflower moves with sunrise and sunset, and Chimonanthus praecox is about to bloom in the slight cold season.

As we all know, there are 24 solar terms in China, and each solar term is divided into three periods, about five days. This is phenology. And each solar term should have its own corresponding flower, that is, 24 Hua Xinfeng. Flowers are flowers because they are more punctual than people. The slight cold solar terms in Hua Xinfeng are plum blossom, camellia and daffodil.
