Its main ingredient is rice slices seasoned with sushi vinegar and keeping human body temperature, and its ingredients are fish, seafood, vegetables or eggs. It tastes delicious and is very popular with people. Sushi was recorded in the Japanese heian period code "Yan Xi Ti", which was completed in 927 AD.
