The soy sauce you said when you were a child is soy sauce. In the supermarket seasoning cabinet, just look for soy sauce. There are too many kinds of soy sauce now, many of them are soy sauce, which tastes fresh and light. Soy sauce is old black soy sauce, salty and has a bean smell. As for vinegar. . I don't like being jealous since I was a child. I haven't studied it. It is said that more than 90% of the current vinegar is blended with vinegar essence. I don't know what the previous vinegar tasted like.
