I'd dispute the claim on China, at least for today's China. Anecdotally, the Chinese are very conscious of their/our "ancient culture" and "proud history".

It's also in state sanctioned ideology too, eg. https://en.wikipedia.org/wiki/Chinese_Dream

`Xi said that the Chinese Dream is the "great rejuvenation of the Chinese nation"`

If more literally translated, this is pretty much the Chinese version of "Making China Great Again".

You're probably correct that this doesn't apply during the cultural revolution (and maybe for the most of the 20th century), but that's like a long gone boomer era.
