On the third Geng Day after the summer solstice in the lunar calendar, the dog days of summer begin.

At this time, the weather is hot, people lose appetite and start to lose weight, which is also called "dry summer".

People began to avoid the summer heat and pay attention to diet and nutrition, and the government also stopped working.

There are three kinds of fresh food in Jiangsu's summer diet: amaranth, broad beans, and almonds on the ground; cherries, plums, and toon on the trees; and sea silk, croaker, and salted duck eggs in the water.

Hangzhou people like to eat black rice. According to legend, it is to commemorate Pang Juan during the Warring States Period.

A folk song from Jiande, Zhejiang Province says, "Start a summer with supplements." This means that supplementation begins in the long summer during the summer solstice.

They usually eat red dates, boiled eggs, and chicken stewed with astragalus to nourish their bodies and prepare for the intense agricultural work in autumn.

There is a habit of eating dog meat in Guangdong.

As the saying goes, "The dogs in the summer solstice have nowhere to hide." If dogs are killed in the summer, they have nowhere to hide, but they cannot be slaughtered at home or processed in the wild.

It is popular in Beijing that "dumplings are served first, noodles are served second, and pancakes are served third"; "the winter solstice is in Jiaozi and the summer solstice is here".

Heatstroke prevention and cooling mainly focus on two aspects: containers filled with ice. First, eat more cold foods, cold foods, and fruits.

Ancient tea fighting and cold soup are excellent anti-heat products.

At the Suzhou Festival, there are seven teas and meals for cats and dogs.

At the same time, eat more jelly, sour plum soup, and ice cubes.

As early as the Zhou Dynasty, there were officials in charge of ice and ice room equipment.

(In modern times, ice flakes were unearthed from the tomb of Zeng Houyi and were used in the form of freezers until modern times.) Ice is stored in winter and eaten in summer.

In the prosperous Song Dynasty, ice drinks were sold on the streets, and shaved ice was available in the Ming and Qing Dynasties.

On this day in the long summer, the Qing court rewarded the Minister of Civil and Military Affairs with ice cubes.

It's the melon season again, and people sit under the melon sheds to enjoy the cool air and eat watermelons.

Watermelon and bitter melon are both foods that clear away heat and relieve summer heat, and are important products during the summer solstice.

In addition, mosquitoes breed in summer and there is a lot of rain, making it easy to contract intestinal diseases such as dysentery.

Therefore, there is a custom of eating green onions and garlic in summer diet.

Li Ming Shizhen's "Compendium of Materia Medica" believes that garlic has the effects of "opening the five internal organs, reaching the orifices, dispelling cold and dampness, avoiding evil, reducing swelling and pain, and transforming meat".

In addition, summer viewing in the exhibition hall is also a summer heat prevention activity.
