As you know, many Japanese cultures have been handed down from China, including writing, Mid-Autumn Festival, China Zodiac and Japanese national gourmet sushi. In Japanese, sushi is represented by Chinese characters "Xi" or "Tai". If you see these two words on the curtain in front of a street shop in Japan, you can definitely eat sushi in it. As early as the third century BC, Lu recorded in China's dictionary Erya Shi Qi that "meat is soup and fish is fish", that is, chopped fish; In the second century AD, the Han Dynasty compiled "Shi Ming-Volume II-History Diet XIII", which recorded that "I also cooked with salted rice and added glutinous rice." Fu is a kind of food made by fermenting and chopping fish with salt and rice. It smells like sushi at this time, but it looks a little messy.

Sushi began to be popular in China in the post-Han period, but in the Song Dynasty, where wars were frequent, it became a necessary delicacy for "getting married and having children" because of its convenient storage. At this time, in addition to fish, vegetables and meat have also become raw materials for sushi. Sushi was really introduced to Japan in the Nara era. Japanese businessmen who have been doing business abroad for a long time like to add fish to rice balls pickled with vinegar as food on the way, which can be preserved for a long time and appetizing, so sushi finally became popular throughout Japan in the Edo period and became a national cuisine. At this time, in China, these two kinds of food have disappeared.

Sushi is just a rice ball wrapped with something edible or delicious.
