Many times liberals and their media/social media within the PRC flare up each time a democrat is elected in the US as they are given funding to spout and spread their bullshit (a term we usually refer to as 'dog food').

To be honest the environment was much worse a decade or more ago. Imagine being denounced as a pinko by Chinese liberals inside the PRC in the 2010s and prior just for saying a single positive thing about their own country lol.

Talked to a few of them recently and hearing their fear of the next generation being so "deeply red" was interesting, because they were hoping that everyone would become even more liberal and end up like Japan, full of pretty anime and pop culture while being subservient to the West.
