Habit: A professor told me that winter in Korea is cold and long, just like the northeast of China. There are no fruits and vegetables, and there were no greenhouse vegetables in the past. Material life is also poor, and there are not many rich people, so Koreans use salt to pickle vegetables for the winter. It can be said that it stems from the compulsion of living environment and the need of survival, and has since become a eating habit.

Habit is a very powerful thing. Koreans can't live without kimchi for three meals a day, from national leaders to the people. There is a Korean proverb: "!" . It means "rice without kimchi". According to statistics, each person in Korea eats 35 kilograms of kimchi every year. Healthy, most Koreans think kimchi is very nutritious and beneficial to the body. Pickle is a fermented food with vegetables as the main raw material and various fruits, seafood and meat as ingredients.

The main ingredient is lactic acid bacteria, which makes people's appetite open before meals and tastes good with meals. It can also be used as a side dish with wine, which is easy to digest and refreshing. It can not only provide sufficient nutrition, but also prevent arteriosclerosis, reduce cholesterol and eliminate excess fat. Therefore, kimchi has been an indispensable dish in Korean diet since ancient times.

Culture, kimchi is not only a side dish, but also a kind of inheritance. A female student once told me seriously that kimchi is related to the dignity of Koreans. Kimchi is not only a dish in Korea, but has been sublimated into a unique tradition and culture. For Koreans now, what matters is not kimchi, but the feeling and dignity of eating kimchi.
