Why do the officers and men who read the National Day wear white gloves and boots?

According to the relevant regulations of the army, if it is an organized collective activity, in order to ensure the unity of the whole army, some of the dressing the don't wear gloves, and some don't wear gloves. For example, you can wear white gloves in a military parade or parade. When individual soldiers are on duty, such as armed police soldiers standing guard in Tiananmen Square, they can also wear gloves distributed by the troops. The same applies to cotton caps. If our soldiers didn't wear gloves and cotton caps in cold areas, they would have been frozen.

Maybe it's tradition.
