That's where it started I think, this is a byproduct of youth thinking that the Chinese belle epoch was the 90s and early 2000s. They are anxious about international isolation, real estate bubble burst and of course the death of lib epicureanism.
It’s quite fascinating how far the human psyche will go to literally rebel against the eyes and ears. Libs in the US see & hear daily decay and call it paradise (or at best IRL glibly shrug and assure themselves it’s the best humanity has). Meanwhile Chinese libs see prosperity and feel doom. I don’t like being wrapped in the contradiction sack!!
