What do you mean, it rains on a hot day, and it's a frost for a hundred days?

It's hot and rainy, and there's a frost every hundred days (the first frost). This is a big summer day and a small summer, drowning mice.

The summer heat is one of the 24 solar terms, and it is also the second half of the official calendar. The arrival time is between July 22nd and 24th in Gregorian calendar, when the sun reaches 120. At this time, it is the hottest period of the year, with the highest temperature and the fastest growth of crops, and droughts, floods and windstorms are the most frequent in most areas. It is very important to grab crops and seeds, prevent drought and drainage, and manage fields. Folk customs include drinking tea, drying ginger and burning incense.
