Note: the word "Li" should be lengthened by 1~2 seconds. The word "positive" should be simple, and an emergency stop is enough. Both words should be loud and at ease: the pronunciation of the word "slightly" should be explosive, crisp and neat, giving people a sense of warning. The word "interest" can be brought out gently, not loudly. Look to the right: "Look to the right ~ ~ ~ Qi!" . The word Xiang is pronounced explosively, extending by 1 sec. Just read the words "right" and "look" together. The pronunciation of "Kan" is slightly larger than that of "Right", and the pronunciation of "Kan" is prolonged by 0.5 seconds. The word "qi" is pronounced crisp and slightly louder. Look forward: "Look forward!" . When Xiang and Qian are read continuously, the pronunciation of Qian is prolonged by 0.5~ 1 sec, and the word Kan is pronounced explosively. Turn back, turn left (right), start walking, go forward and run. See "Looking forward". These passwords are issued by the army, mainly because the soldiers shouted out have a certain sense of rhythm.
