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.
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.
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.
