First link: That is a Swedish robotics blog and the sources linked are just landing pages for Chinese tours or language lessons.

Second link: Where do they say that 'making loud mouth noises is a sign of respect'? They say 'people slurp noodles' which is exactly what I said.

> It's so common that the only logical explanation is that it is encouraged. It appears to be the norm and the non-slurper is the exception. I'm glad that your parents taught you to not slurp. You are an exceptional individual.

Anyway I’ve asked enough Chinese people about it to get the same answer. Not all do it, but some do it for these reasons.

I doubt you ever asked any Chinese.

They are saying it is normal to slurp noodles, which is what I said in my first reply to you. They did not say that they make 'loud mouth noises' as a sign of respect.

Ask this specific question: "Do you make loud mouth noises while you eat as a sign of respect, or is it just normal to slurp noodles?" and see what answer you get.
