Soy sauce It's local pickles. Back in the years of material poverty, the root, the cabbage gang couldn't help but throw away some peanuts and soybeans, put in some seaweeds, boiled with soy sauce and smelly salt. They used to come for pickles, and now they're in a lot of restaurants in the area. I can't eat algae, I don't have seaweed, but I've got seaweed。
