Sting is the third of the 24 solar terms and the beginning of the mid-spring season. The time point is between March 5 and 7 of the Gregorian calendar every year, and the sun reaches 345. In the twenty-four solar terms, the awakening of insects naturally reflects the phenomenon of biological germination and growth under the influence of rhythm changes.

It is the reflection of ancient farming culture on natural festivals, which is of great significance in busy farming. This solar term is also called "Tanabata" in history, and Xia said: Tanabata in the first month. In today's China cultural circle, the Japanese still use the name "Bannerman".

Climatic characteristics

Surprise and thunder attract the most attention. If it thunders before the earthquake, the clouds will not open for 49 days. The "shocking" solar term is the moment when it is cold and warm. According to the cold and warm weather, there are proverbs to predict the weather in the later period: cold scenery, warm spring equinox and so on. The wind of Mantis Festival is also used as a basis for predicting the weather in the later period, such as the north wind blowing after Mantis, the south wind blowing after Mantis in early winter, and the late planting of seedlings.

Modern meteorological science shows that the occasional thunder before and after the sting is due to the increase of the earth's humidity, which makes the hot air near the surface rise or move northward, with strong power and frequent activities. 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. Thunder can be heard in southern Yunnan around the end of 1, and the first thunder day in Beijing is in late April.
