Good Table Manners
Manners play an important part in making a favorable impression at the dinner table. Here are some general rules： Napkin （餐巾） use
The meal begins when the host unfolds his or her napkin. This is your signal to do the same， so place your napkin on your lap. Unfold it completely if it is a small napkin. Or in half， lengthwise （纵向地） ，if it is a large dinner napkin.
If you need to leave the table during the meal， place your napkin on your chair as a signal to your server that you will be returning. Once the meal is over， place your napkin neatly on the table to the right of your dinner plate. Do not refold it.
Use a napkin only for your mouth. Never use it for your nose， face or forehead. Use of utensils （餐具）
Start with the knife， fork or spoon furthest from your plate， and work your way in， using one utensil for each course. If soup is served， remember to spoon away from yourself. This helps stop the drips. Do not put the entire soup spoon in your mouth. Instead， fill a soup spoon about 75 per cent with soup， and sip（啜饮）it from the side noiselessly.
After finishing dinner， place the knife and fork parallel to one another across the plate with the knife blade facing inward toward the plate.
