The use of knives and forks. Hold a knife in your right hand and a fork in your left hand. First, hold the food with a fork, then cut it into small pieces with a knife, and then send it into your mouth with a fork. Europeans do not change hands when using, that is, they hold the fork with their left hand from cutting to food delivery. After cutting, Americans put down their knives and change their right hands to hold forks to deliver food to the entrance.
When knife and fork are used together, the fork posture is similar to holding a knife, but the fork teeth should be down. Usually, the knife and fork are used together when eating the main course, but if there is no need to cut with a knife, you can cut with a fork. Both methods are correct.
Usage of spoon. Hold the spoon with your right hand, and hold the fork with the same method, but your fingers must be held at the end of the spoon handle, and you should not eat other food except soup.
Usage of napkin. When eating, the big napkin can be folded (usually folded in half) and spread out on the legs, and the small napkin can be spread out directly on the legs. Be careful not to hang napkins on your chest (but in places with little space, such as airplanes). When wiping your mouth, use the top of the napkin and use the inside to wipe your mouth. Never use it to wipe your face or clean knives, forks, dishes, etc.
