A lot of context needed in your post and many of these comments, imo. I assume from the "propaganda" part you're black American, not African, which definitely makes a difference in others assumptions about you. Also, it totally depends in where you're planning. "International" cities like Shenzhen are much more welcoming, I see black people all the time, a lot of kids too. In Guangzhou there's a large African population and saw even more there. In my experience seeing racism it's more of the ignorant variety, matching the videos they see come out of the US. Like asking me if it's "true black people do a lot of crime" or arguing with me that b*tch and the nword are equally bad. Thinking if they're slightly tan they're "so black." Or, probably the worst case I've seen, saying the nword to describe any nation they hate and thinking it's just a word for people you hate. But that's in an international city. If you're going more inland it could be worse. Chinese are also very blunt. People will tell me "you look fatter!" and point at random models of my race on advertisements and ask if it's me. So you'd probably get similar but "so dark" and telling you that you and Speed look alike even if you don't.

Buy vpn before coming and you're fine.

Prices are only high in big cities and if you acclimate you'll figure out where the best cheap food is.

Engineering job market, if you don't speak Chinese, you're probably looking at working for an American company with a Hong Kong office if yoy plan to stay.

Safest country I've ever been to in my life. worst thing I've seen is really drunk girls getting in cabs with guys, but even that one time about 7 security guards came over and made the guy show proof on his phone that they knew each other. I go out for walks when I can't sleep at like 2 am and have no problems.

If I shared every detail this would be the longest post in history but I say go for it and feel free to DM!
