First of all, the ancients welcomed summer

In ancient times, there was a special ceremony to welcome summer. Emperors and officials were asked to wear scarlet dresses and Yu Pei, and even horses and car flags were scarlet. Then they went to the southern suburbs of Beijing to hold a ceremony to welcome summer and express their good wishes for a good harvest, because in ancient times, a country's harvest was very important, which led to long summer becoming a very important solar term in their minds, because spring sowing and summer. The emperor will give Wenwu Baiguan ice cubes to relieve the heat, and some people will drink cold drinks to relieve the heat.

The homophonic expression of noodles is that people in eastern Fujian eat light cakes, people in zhouning county eat long summer paste, and people in rural Zhejiang drink seven kinds of porridge. The so-called seven kinds of porridge are to gather the rice of each family, cook it into a pot of porridge, and then share it with you. There are three new things to taste in Jiangnan.

Only in the area south of Fujian will it be a real summer. The temperature is getting higher every day, and green leaves and shadows will be added along the way.
