Why can’t Chinese people make any noise when eating, while in Japan the sound is a compliment to food?

First of all, the cultural differences between the two countries are huge. In China, it is considered impolite to make noise while eating, but there is no such culture in Japan. They like to praise the delicious food while eating.

On the other hand, the sounds we make while eating are a by-product of how we enjoy our food. But do we get the same enjoyment out of the sound we give to others? In fact, most people would be disgusted by it. Why is this?

I've been hearing complaints about this recently. I heard that people are tortured by the sound of apples every day. He described a constant "squeaking" sound and a quick and crisp slurping sound every time he "crouched down," one at a time. It was okay, it almost drove him crazy all day. I sympathize with the “victim,” but I also sympathize with the apple-eater.

Because it reminds me of my father who couldn't stand some noises so we had to put up with strict rules at home.

If we eat apples, they must be peeled and cut into small pieces. It is absolutely impossible to eat them with a big mouth. Don't make any "squeaking" sounds when eating. If we chew instead of snore while eating sugar, our sugar will be confiscated.

Maybe these are nothing. What frustrates me is drinking from a straw, because when we drink from the bottom of the cup, if we use a straw, we suck in the air from the cup. If we make a "squeak" sound, we will be smelly by our father, so we can only watch the last sip, but we can't drink it.

For years I thought this was just a special request for individual families, just like everyone else would have their own requirements. My brother can't stand people eating crackers next to him. I feel uncomfortable when my mother eats toast or porridge next to me, although I don't understand where the discomfort comes from. My ex-boyfriend never cared about other people, no matter what he ate or drank.

He wolfed down food and water while "crouching". Some people might be able to handle it, but I can't. So we usually communicate on the phone, but when I hear him drinking and screaming on the phone, it drives me a little crazy.

This is Chinese-style education.
