In the traditional custom of China, on the seventh day of the Lunar New Year, when everyone celebrates their birthdays, seven kinds of vegetables are cooked into seven kinds of vegetable soup, that is, seven kinds of vegetables are cooked into mixed vegetable soup. In the agricultural society, everyone hopes to eat seven bowls of vegetable soup in the coming year and have a bumper harvest. People eat "seven dishes and one soup" every day, which also means that the new year is over. Tomorrow, the eighth day of the eighth grade, we should pull ourselves together and start working hard.

It is a good omen for people to eat soup made of seven kinds of vegetables when they are alive. It is said that it can eliminate evil spirits and cure all diseases. Different places have different products, different fruits and vegetables and different meanings.

Mustard, cabbage, leek, spring vegetables, celery, garlic and thick-petalled vegetables used in Chaoshan, Guangdong; Hakka people use celery, garlic, onion, coriander and leek to match fish. Spinach, celery, onion and garlic, leeks, mustard greens, shepherd's purse and Chinese cabbage are used in Taiwan Province Province and Fujian Province.

Among them, celery and onion are clever, garlic is good at calculation, mustard makes people live longer, and Hakka people like to cook and eat with fish more than enough. On that day, all rural residents who owe one or two vegetables and collect other people's vegetables and cook seven pieces in the field are not thieves.
