Sushi is a traditional Japanese food. In ancient Japan, sushi was salted fish marinated with salt and rice, which later evolved into sushi today.

Its preparation method is to season with vinegar, sugar and salt, cool the vinegar rice cooked in pearl rice, Japan, which is low in fat and slightly sweet, and add ingredients such as fish, seafood, vegetables, eggs or other meat.

The Japanese often say that "where there is fish, there is sushi". This kind of food is said to come from the subtropical region. People there found that if the cooked rice was put in a clean fish room and buried in the altar, it could be preserved for a long time, and the food would have a slightly sour taste because of fermentation, which was the embryonic form of sushi.

Li Hetai originated in China. Although sushi is a Japanese food, it originally came from China.

Su Shi's other way of writing "Fu" appeared in another dictionary of Han Dynasty in China in the 2nd century more than 500 years later. Liu Xi's "Ming Shi, Volume II, Thirteen Interpretations of Diet" records: I cooked it with salted rice, too. It means that fish is preserved with salt, rice, etc. Fermented and chopped, cooked and eaten.

One hundred years later, Chinese characters spread to Japan, and the words "Li" and "Tai" have been confused. China also stopped using rice to brew food. In the Ming Dynasty, scones and scones disappeared from Chinese food.
