Have visited China often. My major gripe to living there would be digital freedom and surveillance - unlocking bootloader,etc are heavily restricted there. Plus the GFW, which does prevent the population being psyop'd by foreign social media, but is a small pain if you need to use outside services.

That doesn't really affect my daily life though, especially for someone born there. If it's the tradeoff for the other aspects (high public safety, developed infrastructure...) then I would consider accepting it.
