Roland Boer who has written extensively about China, write in his 2021 Springer book Socialism with Chinese Characteristics. A Guide for Foreigners, p. 281:
For Xi, the people’s standpoint (lichang) is basic and foundational (genben). [...] The original desire and the mission are, of course, one and the same: Communism. [...]
I could draw upon an impressive array of internationally collated surveys on confidence in the direction China is going, on trust in governance and public institutions, or in approval of the way the COVID- 19 pandemic was handled in China (Ipsos 2019; Edelman 2020; Cunningham et al. 2020). In all such surveys, we repeatedly find a percentage range from the 80s to the 90s for confidence, trust, and approval among the common people for governance as such.
But I would like to add some anecdotal evidence from reasonably extensive engagement with common people (laobaixing), with urban and rural workers. Perhaps a decade ago, the joke among such people was that the government might say it is focused on the renmin, the people, but that it was actually concerned with the renminbi, the alternative name for the Chinese yuan. In the last few years, I have noticed a distinct change: now people increasingly feel Xi is ‘pretty good [bucuo]’. How so? He invokes Mao Zedong and is felt to have the common people’s interests at heart.
Is this true? Do all surveys indicate that the CPC and/or the Chinese government enjoy 80% to 90% domestic approval rating on practically any topic/issue?
(Side note: I've chosen this as a more serious claim of what's heard in songs, etc., which however tends to have a more personalist angle.)
If you think I'm overinterpreting the quote (in formulating the title of this Q), then answer according just to the enumerated claims: "confidence in the direction China is going, on trust in governance and public institutions, or in approval of the way the COVID- 19 pandemic was handled in China" and "confidence, trust, and approval among the common people for governance as such" (whatever "as such" you think it means.)
