When spring comes, you can eat more vinegar, of course, without stomach trouble.

One of the reasons is sterilization, because everything revives in spring, including bacteria, so sterilization with vinegar can reduce the problem of food spoilage to some extent.

The second is refreshing. If you don't feel the dawn in spring, you will be sleepy and jealous.

The third is to stimulate appetite. Some people who are sleepy in spring have a bad appetite. Vinegar can be used to stimulate appetite.
