Is the Great Heat the dog days of summer?

Definition and analysis of Dashu:
The Great Heat solar term is the hottest solar term in the year. The ancient book “Explanation of the Twenty-Four Solar Terms” says: “The Great Heat is the hottest solar term.” This is enough to illustrate how hot this solar term is. The reason why it is extremely hot during the "Great Heat" period is that since the beginning of summer, the heat absorbed by the ground from sunlight during the day is more than the heat released at night, and the heat continues to accumulate. During the Great Heat period, the accumulated heat reaches its peak, so the Great Heat period is the hottest.
Definition and analysis of dog days:
The "Three Fu" refers to the first, middle and last Fu, which is approximately from mid-July to mid-August. After the summer solstice, although the days become shorter and the nights become longer, the days are still longer than the nights. The ground still absorbs more heat than it emits every day, and the temperature near the ground becomes higher day by day. During the "dog days", the heat absorbed by the ground is almost less than the heat emitted, and the weather is the hottest. Later on, the heat absorbed by the ground began to be less than the heat emitted by the ground, and the temperature slowly dropped. Therefore, the hottest time of the year usually occurs during the "three hottest months" of summer.
The Great Heat solar term falls in the middle of the dog days, so it is the hottest time of the year. However, the Great Heat and the dog days are two different concepts. The Great Heat just happens to fall in the middle of the dog days.
It is not true that the Great Heat always covers the dog days of summer. This statement is wrong!

About the Great Heat Solar Term

Shu means hot. Indicates that it is the hottest solar term in the year.
Generally speaking, the Great Heat solar term is the period with the most sunshine and the highest temperature in the basin in a year. It is also the period with the most abundant rainfall, most common thunderstorms, and the most concentrated number of days with high temperatures above 30°C in the western part of the basin. It is also the period with the most frequent high temperatures above 35°C in the eastern part of the basin. High temperatures around the time of the Great Heat are normal manifestations of the climate, as higher temperatures are conducive to the flowering and filling of spring crops. However, if the temperature is too high, the growth of crops is inhibited and the rice setting rate is significantly reduced.
After the dog days of summer begin in the western part of the basin, light, heat and water are at their peak of the year. The three promote each other and form good climatic conditions for the growth of spring crops, but attention should be paid to flood prevention and drainage. At this time, high temperatures and long sunshine are often accompanied by little rain in the eastern part of the basin, which not only limits the advantages of light and heat, but also aggravates the adverse effects of summer drought on spring crops. In order to resist summer drought, in addition to paying attention to water storage in the early stage, we should also improve crop cultivation measures according to the climatic characteristics of the eastern part of the basin, focusing on "early" to seek benefits and avoid harm.
The hottest day of the year is the season when jasmine and lotus flowers bloom. The sweet fragrance of jasmine becomes stronger as the weather gets hotter, giving people a clean and fragrant enjoyment.
The noble lotus is not afraid of the scorching sun or sudden rain. It blooms in the morning and closes in the evening. The poet praises it as "the lotus flowers are especially red in the sun." The vibrant midsummer is pregnant with a good harvest.
