Why do few people in China wear cheongsam for daily activities?

Because cheongsam was a popular dress in social occasions during the Republic of China, but now, this kind of dress has become less and less common, especially in some formal occasions, few people wear this kind of dress. We can only see these things on some TV or from some fashion exhibitions, because it is no longer suitable for this era, and everyone does not recognize him, so no one will persuade him. I think this is also the progress of human society.
