The language in China is constantly developing and changing. Is the rhythm of classical poetry changing?

I personally don't think so. I think I can proudly say that Chinese is the most simplified language among the major languages at present. Chinese characters have been written for thousands of years, and the changes here are all in the same strain. Even in another 5000 years, I think Chinese characters will change in the same way. Ancient sometimes does not mean backwardness and conservatism, but a symbol of super vitality.
