Is it always spring in the long summer?

According to the ancient classification method, long summer is long summer, so the day before long summer is spring.

Similarly, according to the lunar calendar, the long summer is in May, and the day before is naturally summer. However, according to other classification methods, it is still spring. Especially now, we generally divide the four seasons according to the weather temperature of the meteorological department, and the national average temperature before and after the long summer is 18℃-20℃, which naturally fails to reach the summer standard of 22℃, so it is considered as spring, but it is also possible for the southern region to enter summer ahead of schedule.

Long summer is the first solar term in summer, which means the beginning of summer, and spring is about to leave, after which the temperature will rise obviously.
