Important. Too high elbows on both sides will make the knife and fork angle too large and upright; On the contrary, if the elbow is too low, the knife and fork will fall off, so there is no way to cut vegetables correctly. Relax your shoulders and wrists, don't open your arms, and keep the angle between the knife and the plate at about 15 degrees. Here is a summary of seven points: sitting and cooking; Relax your shoulders and wrists; Keep your arms close to your body; Elbows should not be too high or too low; Knife and fork tilt to the plate; Hold the plate tightly with a fork; Move the knife gently, but hold it firmly. This not only makes it easy to cut food, but also looks quite elegant. The way the knife moves also makes sense. First, push hard on the fork in your left hand, and then move the knife gently. Be careful not to use force when pulling the knife backward, but to use force when pressing the knife forward, so as to cut the food neatly. When the elbows on both sides are too high, the angle between the knife and fork will be too large to cut the food neatly. Knife and fork should not be tilted too much. The fork can be changed freely according to the characteristics of cooking, which is convenient for eating. When eating with a fork, the back of the fork must face up. However, when eating with a spoon, the fork should face up. Different from chopsticks, the fork can rotate up and down according to the cooking characteristics, which is convenient to use. You can't change the position of the set tableware at will, but if you are left-handed, you can exchange knives and forks when eating. Only after eating, tableware must be placed according to the usage of right-handed people, and the handle of knife and fork should be placed on the right side of the plate. The main reason for this is not to bring trouble to the service personnel.
