What do the solar terms Song Zhongliang and Lu Xiu stand for?

In the solar term Song Dynasty, coolness represents shock, and dew represents white dew.

Sting is one of the 24 solar terms. Every year when the sun runs to 345 degrees of the Yellow Meridian, it is called stinging. At this time, the temperature rises rapidly and spring thunder sprouts. "Sting" refers to the activity that small animals burrow into the soil for the winter and are awakened by Lei Zhen.

"Spring thunder rings, everything grows", and it is a fine sunny day in September, with the temperature rising and the rain increasing. Except for the northeast and northwest regions, the average temperature in most parts of the country has risen above 0℃, and the average daily temperature in North China is 3-6℃.

After the Millennium, China really entered autumn, and the temperature began to drop gradually. People can clearly feel "an autumn rain and a cold". The proverb also says, "If you don't show your body in the Millennium solar terms, you will come to Ding Ning sooner or later." This is telling people that although the day is mild, it is already very cold in the morning and evening, and it is easy to catch cold with bare arms.
