I agree with everything, especially the point about society, because China truly has huge problems with this, the so-called "problems of social morality" in China, due to rapid urbanization and a lag in the development of social behavior. I'm not a scientist, I'm just someone who works in the entertainment industry in China, and in my personal experience, 80% of people leave China precisely because of "low moral character" (that is, low moral character, not in the sense of being robbed on the street like in Barcelona, but in social interactions). Japan is good for its manners, but terrible for foreigners in terms of integration into society. China readily accepts foreigners, and they can become part of the community within a year, but the everyday environment is difficult for newcomers to adapt to. Slurping, spitting, loud conversations, chaotic driving, and trash don't add to the appeal. Yes, I didn’t describe Paris, they have the same problems, but China is not France, and it must somehow improve the quality of its citizens, as they did in Singapore.
