This solar term is also called "Qixi" in history. "Xia Zheng Xiao" said: "The first month of the month began to sting". In today's China cultural circle, the Japanese still use the name "Kai Zhe".

The sixth generation emperor of Han Jingdi, Han Jingdi, taboo for "Qi", in order to avoid taboo, changed "Qi" to "Jing" with similar meaning. At the same time, the order of Meng Chun's first month's fright and mid-February's spring festival "Rain" was also replaced. Similarly, the order of "Grain Rain" and "Qingming" has been replaced.

Before the Early Han Dynasty: beginning of spring-Qi Zhe-Rain-Equinox-Grain Rain-Qingming.

Emperor Wu of the Han Dynasty: beginning of spring-Rainthorn-Equinox-Qingming-Grain Rain.

After entering the Tang dynasty, you don't have to avoid the word "qi" and use the name "qi". However, due to some unaccustomed reasons, Dayanli once again used the word "elite", which is still in use today. Like China, Japan used "Jingzhe" in the calendars of past dynasties. Since then, Japan has also adopted Dayan calendar and Xuanming calendar. When changing the calendar to the truth, Japan began to use the name "flag bearer".

The meaning of fear:

"Sting" means "hiding". In winter, insects hide in the soil. "Surprise" means "wake up". Spring thunder in the sky woke up the bugs. The so-called "spring thunder" means that when the spring thunder begins to sound, it wakes up the stinging insects that are dormant in the ground for the winter.

In some ancient places, people smoked the four corners of their houses with incense and wormwood to drive away "snakes, insects, mosquitoes and rats" and musty smell. Over time, it gradually evolved into the custom of shocking and beating villains to drive away bad luck.

The symbolic feature of the shocking solar terms is that spring thunder suddenly moves and everything is full of vitality. Judging from the natural phenological process in various parts of China, due to the large span between north and south, the time when spring thunder begins to ring is different in the morning and evening.

China has a vast territory, and there is a big difference between the north and the south in the progress of entering the spring. During the period of fright, the territory of spring obviously expanded northward, from central Hubei and northwestern Jiangxi to northern Henan and southwestern Shaanxi. At this point, most of the south has entered spring. Although it is still winter in most parts of the north, it will be much warmer.
