Scary solar terms are of great significance in agriculture. Since ancient times, the working people in our country have attached great importance to the solar terms of fright and regarded it as the spring ploughing season. In the traditional culture of China, location is associated with gossip and official time. When the barrel handle points to the east, divination is in the earthquake position, which is for Uzuki (Mid-Spring Moon). When everything came out, the world changed. In the twenty-four solar terms, the fright reflects the phenomenon that natural creatures germinate and grow under the influence of rhythm changes.

Thorns and thunder are the most striking. For example, "it thundered before the earthquake, and the clouds could not open for forty-nine days." The solar term of fright is in the middle of cold and warm weather. According to the cold and warm weather, there are proverbs to predict the weather in the later period: "Cold fright, warm spring equinox" and so on. The wind with prickly knots is also used as a basis for predicting the weather in the later period. For example, "if you are afraid of the north wind, you will spend the winter from the beginning" and "if you are afraid of the south wind, you will plant seedlings later".

Modern meteorological science shows that the occasional thunder before and after the "wake-up" is due to the increase of earth humidity, which leads to the rise of hot air near the surface or the strong and frequent northward movement of hot and humid air. 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.
