1, the summer heat is not falling. The first fall is between the summer heat and the solar terms of the summer heat. After the summer heat, the temperature begins to rise continuously and slowly enters the summer heat period, but the dog days refer to the hottest period of the year, and the summer heat is not the hottest time. Therefore, the summer heat is not a dog day.

2. The solar term of Little Summer is the fifth solar term in summer. The explanation of the solar term of Little Summer is described in twenty-four solar term: Little Summer, June Festival. Summer heat is also hot. In the heat, it is divided into sizes, small at the beginning of the month, large in the middle of the month, and still small today. Therefore, a little summer heat can be understood as a little heat, but it is not the hottest time of the year. There is an idiom "cold comes and summer goes", in which "heat" also means heat. However, this heat is a little different from what we usually understand. It means "hot". Because during the summer solar term, most parts of the country have entered the midsummer.
