Agree that markets selling live animals should be banned or at least monitored more strictly. Do not think the other two points are relevant. Regarding cities, if you look at Chinese society and economy, urbanization is a very positive force that contributed hugely to people's wellbeing, including health. Also BTW Chinese cities are probably the safest cities in the world. Regarding hukou, it limits access to education and house/car buying, much more than healthcare access. Actually a lot of rural residents routines go to big cities to get healthcare service.
