Is the soup in the pot-stewed restaurant always the same?

Don't talk nonsense if you don't understand. The longer the marinated soup is, the better it tastes. Cook once a day in summer and once every two days in winter. You should cook every day. Even if you don't cook, you have to cook the pot, so it won't go bad at all. The marinated soup in my shop has been used for many years, and it has been more than 70 years since I brought it. I have used it for three or four years.
