What are the similarities and differences between China pop and Japanese pop?

If it is ancient music, China's music is mostly magnificent, while Japanese music is soft, and most people will think it is a lullaby, which has a lot to do with the territorial areas of the two countries.

If modern, there are good songs, Japanese anime songs is world-class, and there are many singers of China songs, but most of them are not good, and the rest are excellent.
