Is it warm when the weather is cold?

Jing Ke, also known as "Qi Zhe", is celebrated every year from March 5th to 6th in the Gregorian calendar. It's time to get up, and the weather is getting warmer. Spring returns to the earth, and spring thunder gradually rises, awakening insects that hibernate underground for the winter. As the name implies, this solar term is characterized by the sudden movement of spring thunder and the vitality of everything.

From the natural phenology and climate processes in various parts of China, it can be seen that "thunder begins with your surprise", which coincides with the natural rhythm in some parts of southern China. Northerners want to hear spring thunder until April, and people in the south of the middle and lower reaches of the Yangtze River are more likely to hear thunder when you are startled.
