Origin of ground soy sauce: China has cultivated soybeans for more than 5,000 years. During this process, soybeans are processed into various products, and in this production process, there will be a lot of dross. Later, people felt that it was too wasteful to throw away the dross, so they decided to add seasonings such as sugar and salt to the dross for further processing, resulting in ground soy sauce.

The difference between ground soy sauce and other soy sauces is like soybean sauce, and bean products such as flour soy sauce can see the shape of soybeans, but ground soy sauce is made of dregs, so the shapeless paste on the appearance is slightly heavier than other soy sauces.
