Why do some people like to make a loud noise when eating?

Because they're chattering. Open your mouth to eat and chew. Not shut up and eat. It's not pretty, and the sound is annoying. Especially the sound of some people drinking porridge is even more terrible. They are used to chewing with their mouths open and sucking porridge spoons. Make a purr.

This is related to the habit formed since childhood. It is better to pay attention to correction. Form good habits.

Western countries hate eating and making noise. That's rude. Eating in restaurants and cafes in European countries is so loud that many people will look at you with displeasure. Especially after eating, chewing the fruit, dessert and mouth one by one will cause onlookers. It is also impolite to stretch while eating.

As for the quality of personal cultivation, it may be better to chew with your mouth closed, but you don't realize that there will be noise. Sometimes eating loudly will affect others' appetite and make them feel unable to eat.
