Eating with tight lips is a table etiquette, which indicates a person's quality and cultural accomplishment to some extent. Eating with a "small mouth" not only overcomes the bad eating habit of "wolfing down", but also avoids the harsh noise from teeth and food.
"Big mouth" drinking water has its health-care meaning: water is the best drink and contains no calories. It is much cheaper than fruit juice drinks and cola drinks sold in the market, and it will not have the feeling of "getting angry" or "getting more thirsty" like drinking fruit juice and other drinks.
Drinking water with a big mouth means drinking as much water as possible. Drinking more water can play a certain role in beautifying skin and building body. Some people say, "If I don't eat, I will gain meat even if I drink cold water." This is just a joke. The person who said this didn't actually do what he said. If he does, then "drinking cold water" will certainly satisfy his wish.
Drink water with your "big mouth", which also means that you should drink water often. Drinking water regularly can play a health care role such as removing fire and toxic substances, removing dirt in the body, accelerating human metabolism and maintaining skin elasticity.
Drinking water also refers to drinking tea and drinking delicious vegetable soup or broth. In particular, some professionals should pay more attention to drinking more water. For example, workers engaged in laser phototypesetting, because they have been exposed to computer screens for many years, should always drink more tea and water, so that harmful substances entering the body can be discharged as soon as possible.
