As we all know, in the military parade in our country, not only a large number of male soldiers will line up neatly, but also some beautiful female soldiers wearing short skirts and boots and berets. These female soldiers will not only show a very confident and straightforward image, but also walk in the phalanx as well as the queue that male soldiers walk out of. At the same time, they will also attract people's attention because of their distinctive clothes. As we all know, there are accessories such as stockings and boots, but why nail three nails in the sole of a good boot? There are two main reasons:

First: non-slip.

What is a military parade? The military parade is a demonstration of a country's military strength, which can show China's armed forces, China's strength to the country, its citizens and other countries and organizations in the world. It can unite the cohesion of the people of China, fill people's hearts with national pride, and inspire and inspire the confidence of people of all ethnic groups throughout the country to work together for a better future. However, the military parade consumes a lot. Now China is a small celebration every five years and a big celebration every ten years. This shows how precious this opportunity to show our strength is. Therefore, our soldiers are absolutely not allowed to make mistakes in the military parade. This nail has its function. The ground around Chang 'an Avenue is slippery. Therefore, we need to nail three nails at the bottom of female soldiers' boots to prevent soldiers from slipping during the military parade, which is absolutely not allowed. It can be said that it is a preventive measure.

Second: improve the pedaling.

As we all know, the movements of all soldiers in the military parade are uniform, fast and powerful, which depends on the hard training of soldiers at ordinary times, and will produce clear and loud stepping sounds: step, step, step ... Of course, the sound of people stepping normally is not as loud as expected. Because of the three nails on the bottom of soldiers' boots, we can clearly hear the sound of stepping when watching the military parade on TV.

These two are the reasons why three nails should be nailed to the soles of female soldiers' boots during the military parade. The purpose is nothing more than the heroic spirit during the military parade, but I don't know why three nails have been nailed ... Now the National Day is coming, I wish the motherland prosperity in advance, and I love you China.
