On weekdays, it is normal for us to drink water from cups, but there are always some people who like to get into a dead end and drink water from a bowl for eating. Although this has little impact on people's health, it still affects their image.
Generally speaking, drinking water from ceramic and glass cups is the healthiest. Never use plastic cups or stainless steel utensils to hold water. Plastic cups will suck out some harmful substances and stainless steel cups will rust.
