I used to put oyster sauce, vinegar and sesame oil when mixing cold dishes. Oyster sauce has a slightly sweet flavor with a fresh taste, which can play the effect of sugar and MSG. If the taste is heavy, you can add salt appropriately. If you don't use oyster sauce, I will add a little sugar when I add salt, which can play a role in enhancing the flavor

Abalone juice, fresh shellfish, pepper oil, garlic oil, sesame oil, consuming oil, chicken broth, I usually use these Oh.
