Let's take religion as an example. In Malaysia, Taiwan, and Singapore, traditional temples are still "alive" with popular and active ceremonies, while most temples in China I went are just dead buildings: people lived there and do things have nothing to do with divine, CCP-permitted official events, foreign tourists, modern decorations that have no integrity, etc.
It's just sad to see those religious sites dying. The spiritual essence died, during exactly the Cultural Revolution.
If you mean buddhist temples, that's at max 2000 years of history.
I also had this view that buddhism is a faith that promotes peace - which might be true, but you still have the same human beings behind it. History proves my naive idea wrong.
