Sushi? Was this kind of food originally a traditional Japanese food or was it introduced to Japan from China like ancient culture? Feeling day

Sushi is one of the traditional Japanese favorite foods. The main ingredient is cold rice seasoned with vinegar (vinegar rice for short), and the ingredients are fish, seafood, vegetables or eggs. It tastes delicious and is very popular with the Japanese. The Origin of Sushi/kloc-More than 0/800 years ago (the post-Han era), sushi had been circulated in China, and it was introduced to Japan in 700 AD (the Nara era). At that time, some business travelers pickled rice balls with vinegar, added seafood or meat, and pressed them into small pieces as food along the way. Later, it was widely circulated in Japan. At that time, people were stabbed with various ingredients, known as "Edo Sanlu", also known as "holding land", which is the most popular sushi now. In modern Japanese sushi, there are two kinds of sushi: roll sushi and box sushi. "Roll up" means wrapping cucumbers, tuna, eggs and pickled radishes with seaweed. "Curling" can be divided into two types: too large and too thin. As the name implies, there are differences in size. Box lunch sushi "Box lunch sushi" is named after putting rice in a wooden box, spreading various ingredients, covering it with pressure, and then taking out the wooden box sushi and cutting it into pieces. "Handroll" is actually a kind of "roll". It is said that in the18th century, those Japanese gamblers wandered around the real armor all day, excited and afraid of starvation, so they put tuna meat in their rice and rolled it up with purple cabbage. Stuttering can kill two birds with one stone and prevent rice grains from sticking to poker and fingers, so it is very popular with gamblers. This food was born in the casino, hence the name tekkamabi, and gradually evolved into today's hand roll. The earliest sushi The earliest sushi is a small food made of rice, raw fish and sauce, which can be eaten in one bite. There are many kinds of sushi now, which can hold many things, but you must eat it all at once. Japanese sushi was recorded in heian period under the code name "Yan Xi Style" and completed in 927 AD. Sushi at that time refers to a way to preserve fish. Rub the salt on the fish, press it with a heavy object and let it ferment naturally. You can eat it when it is sour. It tastes good. It is said that this way spread from China to Japan. This method is time-consuming and laborious, and soon developed into a simple way to soak fish in vinegar.
