What is a vest?

As the name implies, "vest" should be related to horses. In ancient times, it did refer to the armor of war horses, such as "Water Margin" 55 times "5 thousand pairs of ripe leather vests." Later, in order to facilitate combat, the Qing soldiers wore a sleeveless short armor, which looked like a war horse's vest, also called "vest". Later, the "vest" that people wear every day is also called "vest". Now refers to the network language. For example, you registered two numbers on a platform, a big one and a small one, and the small one is your vest. Ha ha!
