To answer your question, we must first understand that Japanese is a kind of writing with both pseudonyms and Chinese characters.
Japanese and Chinese are two language systems, just like Chinese and English. English is written in letters, and Japanese is also written in their set of letters called "pseudonyms" For example, the verb "thorn (dual of Cantonese)" is pronounced as "Susa/Sass" in Japanese, while it is written under a pseudonym as "さすさし" in Japanese.
But Japanese culture is deeply influenced by China, so that they use many Chinese characters to write Japanese. "Opposition" can be written as "さす /さし" or "thorn/thorn し", and the Japanese pronunciation is still "Susa/Sasi".
Back to sashimi. Sashimi is "Sashimi" in Japanese. It is written under the pseudonym "さしみ", but Chinese can also be written as "sashimi" (the Chinese character "Ti" in Japanese can be pronounced as mi), which is just for phonetic notation and has no special meaning.
Similarly, "sushi" is the same. The Chinese character "sushi" is just a phonetic symbol, which has nothing to do with the Chinese word "longevity".
These Japanese-style Chinese characters were sent back to China Cultural District in the process of cultural exchange, and China users read them with their Chinese pronunciations, becoming "sashimi", "hand-torn" and even becoming a part of Chinese vocabulary. This phenomenon is called "reverse input" of Chinese characters.
Mon sense, sashimi, also known as raw fish, was called fillet, fillet or silver carp in ancient times. It is the general name of food eaten with fresh fish and shellfish sliced raw and dipped in seasoning. Originated in China, and then spread to Japan, Korean Peninsula and other places.
Sashimi, or the transliteration of Shasimi, is a Japanese food, namely sashimi. Fresh fish and shellfish are cut into raw slices and dipped in seasonings such as soy sauce, mustard and miso.
Sashimi is written in Japanese and sashimi is written in Chinese.
Supplementary explanation:
Because the two fields are the same, raw fish is sashimi, and sashimi is raw fish, two names. ,
