I would also like to see the source

Here's the Harvard study I'm referencing.

We find that first, since the start of the survey in 2003, Chinese citizen satisfaction with government has increased virtually across the board. From the impact of broad national policies to the conduct of local town officials, Chinese citizens rate the government as more capable and effective than ever before. Interestingly, more marginalized groups in poorer, inland regions are actually comparatively more likely to report increases in satisfaction.

This puts the 2016 central government satisfaction at 93.1%, Provincial at 81.7%, County at 73.9%, and Township at 70.2%. 75.1% of respondents also replied that they were "satisfied with eventual outcome" after an interaction with a local official.

Now granted this is all pre-COVID, pre-Xi Jinping's third term, Pre-Hong Kong protests - but also pre-elimination of absolute poverty, pre-green energy revolution, and pre-massive rise in worker wages.
