Why do middle school students seldom wear traditional black belts now?

1. Because middle school students are the younger generation, young people are very fashionable now, and the traditional black belt is old-fashioned, of course I don't like it.

2. Because the old style is not popular, the proportion of manufacturers producing this kind of belt is also small, and few people buy and sell it in the market, so few people use it in circulation.

I still like the traditional button belt, which is tight and safe, but it takes a long time to find a new one every time it breaks down.
