Etiquette: Etiquette volunteers have no dance performance task, but in order to improve the overall aesthetic feeling of etiquette, dance and physical training are essential. Standing: Standing in high heels with a book on his head and an ordinary A4 paper between his knees. Neither books nor paper will fall off. Time: one hour later. Location: indoor and outdoor uncertain. If the teacher is in a bad mood, the sun is indispensable. Smile: the standard is to show 4~6 teeth. The secret taught by etiquette teachers is: when practicing smiling, bite a chopstick to find the feeling in your mouth! Then, smile at yourself in the mirror first, and then work in pairs, face to face, and cooperate with each other to correct each other's "teeth" and make the smile the most standard and natural. Tray: the action is refined to centimeters! Punch your arm from your side waist, and don't show your thumb when holding the tray. Standard posture "weight-bearing" exercise is essential in training. You can refer to the scene where a waiter in a star-rated hotel successfully lifts three bottles of beer, but you must ensure that your body does not shake at all during the practice. Rhythm: control the rhythm to ensure that the prize has just been received. No matter how far you go, the distance between several emcees must be controlled between 30-40 cm. At the same time, we should always pay attention to the pace of awarding prizes to guests to ensure that the tray can not collide with the guests. [ 1]
