There are "three summers" in the 24 solar terms, that is, little summer, big summer and midsummer, which are early summer, heatstroke and late summer respectively.
3. There is also a "beginning of autumn" solar term in the middle of the "Three Summers", followed by beginning of autumn is summer (the last summer). "Three summers" and "three days" both represent hot and humid weather, and the summer days in the 24 solar terms are longer. The length of summer days is beneficial to the growth and yield of crops, and crops should have enough growth time and heat.
