Chinese eating rules have a long history, just like a special story passed down. In China, there are many important eating manners we should follow. Among them, there are some key ones to follow. Let's learn together.
First, it's bad manners to start eating before everyone sits down. You should also let the elders eat first to show your respect. In a family dinner, kids wait for grandparents to pick up chopsticks first. It shows our respect to the elders.
Second, you should use chopsticks rightly. Don't point at others with chopsticks—this is rude. Also, knocking at plates and bowls with chopsticks is not allowed, as it's like what beggars(乞丐) did long ago. If you want to serve food to others, it's better to use serving chopsticks.
Third, when you eat, don't make too much noise. It's better to chew(咀嚼) with your mouth closed to show good manners. And don't speak when your mouth is full of food.
Last, don't reach across the table for food. If there's a turntable(转盘), wait for it. Without a turntable, ask someone next to you for help.
These manners make meals happy and respectful. Let's follow them, and share the beauty of Chinese culture!
