The scorching sun is like fire, playing the solar terms.

The scorching sun is like fire, making a solar term: hot summer or dog days. See "The Water Margin" for this poem, and Bai Sheng sang it fluently when picking wine for his post. It's probably a folk song in the Song and Yuan Dynasties. When writing about the summer drought, the contrast of different moods and attitudes between farmers and Wang Sun reflected the class contradictions in feudal society at that time.

Summer is the twelfth solar term among the twenty-four solar terms and the last solar term in summer. The ecliptic of the sun is 120, which is from July 22nd to 24th in Gregorian calendar. "Summer heat" is heat, and summer heat is extremely hot. Summer heat is hotter than summer heat. Summer heat is the most intense and hottest solar term in a year, and "hot and humid steaming" reaches its peak at this time. Climatic characteristics of the great summer heat: high temperature and intense heat, frequent thunderstorms and typhoons.

The summer solar term is the hottest time of the year, just before and after the "midsection" of the "dog days". In summer, the sun is like fire, the temperature is high, the humidity is high, and there is much rain. Although it is inevitable to suffer from high temperature and humidity, it is very beneficial to the growth of crops, and crops grow fastest during this period.

Since ancient times, there has been a folk custom of drinking herbal tea (tea) in the dog days of midsummer; Fucha, as its name implies, is a kind of tea to drink in dog days. This kind of tea boiled with Chinese herbal medicine has the function of cooling and dispelling summer heat. In addition, there are customs such as burning incense and drying ginger. "Great Summer" is the hottest and wettest season of the year, and the focus of health care at this time is "heatstroke prevention" and "dampness elimination".
