In judo training and competition, in order to show respect for each other, it begins with etiquette and ends with ceremony. Etiquette is divided into standing ceremony and sitting ceremony (also known as "kneeling ceremony"). (1) attention ceremony: 1. The body is in a natural standing posture, feet and heels are relatively side by side, knees are straight, and eyes are fixed on each other. 2. Bend the upper body forward about 30 degrees, droop your arms, put your fingers on the thigh above the knee joint, take a break, then naturally lift the upper body and return to the original position. The speed is about between one breath (about 4 seconds). Note: 1. Keep your back straight, lower your chin, keep your head straight, put your fingers together and straighten, gently stick them on both sides of your torso and salute respectfully. 2. Pay attention to prevent hunchback, head not straight or too low, feet apart or knees bent. (2) Sitting ceremony: 1. Starting from the standing position, take a step and a half back with your left foot. 2. Kneel on your left knee at the position of your left toe. 3. Then retract your right foot, kneel side by side and touch the ground with your toes. 4. Overlap your thumbs, press your right thumb on your left thumb, and sit in a kneeling position after holding out your chest. Sit: 1. Put your fingers together gently and put them on the inner thigh (groin). The distance between knees is two fists wide. 3. The method of folding two feet is to press the right thumb on the left thumb. 4. Keep your back straight, tighten your chin, gently close your mouth and look at the horizontal line. 5. Don't overlap your whole feet, and don't stoop. Side, shoulders down or chin up. Salute: from the sitting position, put your hands in front of your knees, put your fingers neatly together, and put your thumb and forefinger opposite each other, with a distance of about 6 cm, and naturally put them on the mat. Gently lower your head, about 30 cm away from your hands, and salute. After the ceremony, get up and sit up straight. Note: 1. Don't lift your hips off your heels when saluting. 2. When saluting, don't stoop, don't bow your head excessively, and avoid letting the other person see the back of your head. Don't lift your chin, don't look up, and don't have too wide hands. From sitting posture to standing posture: 1. Start from the sitting position, straighten your waist and stand on tiptoe. 2. The right knee is upright, and the right foot is placed slightly in front of the right knee. 3. Move your body center of gravity to your right foot and then stand with your left foot forward and side by side with your right foot. Return to the natural standing posture at the beginning. Note: When standing up or sitting, don't shake your body or look around. The action should be serious, earnest and polite. Courtesy of training ground: At the beginning or end of training, the two sides salute each other 4 meters apart (to stand at attention or sit upright). Everyone should salute when entering or leaving the training ground or in the training ground. Stand up straight when the other person is standing, and sit up straight when the other person is sitting. Nod when walking in front of others.
