As an anecdata point, I recently asked a person who lives in Shenzhen the same question -- what is the broad public sentiment about the HK protests in the PRC, and how much information do ordinary people in general even have?

I was told that people who live near HK can get HK TV and radio, which carries substantially the same news information about the protests as in western media, and this group has a variety of opinions.

Outside that area immediately adjacent to HK, I was told around 80% of people are unaware that protests are happening in HK at all, and most of the other 20% believe the protests are a western plot to undermine Chinese sovereignty.

I cannot vouch for the accuracy of this information, of course. It's one data point from one person.
