10/day The National Day has just ended, and a grand military parade was held in China. Many people in China went to the scene to watch the military parade. Even if some people didn't have the chance to go to the scene, they watched the live TV parade at home. I don't know if you have noticed that during the military parade, the PLA soldiers kept shouting the password of 1234 and 1234 as soon as they appeared, and walked with uniform steps. I believe everyone will. Actually, it's not. PLA soldiers have been trained for many years, so there are other reasons why they need to shout passwords to make the team walk neatly. The reasons are as follows.

The first point: shouting passwords can make people feel more imposing. During the military parade, you can see the uniform steps of PLA soldiers, which are very handsome and the sound of shoes is loud. At this time, the sound of shoes and passwords mixed together can give people a sense of shock.

The second point: shouting passwords can reduce tension. Although PLA soldiers train for a long time every day, it is inevitable that people will be nervous in such important activities as military parade. After all, with so many pairs of eyes looking at you, everyone will be nervous. At this time, the soldiers can relax by shouting the password, so as to walk out of a better pace.

The third point: habitually shouting passwords. In the usual training, the first step will definitely make everyone keep up with the password. Over time, the soldiers naturally formed this password shout 1234. The password will not affect anything, but it will appear more imposing, so they will shout 1234 during the military parade.
