1) Beautiful scenery. With its huge landmass and diverse geography, China has some stunning places. Sure, some parts of China are polluted and ugly. And the US doesn't lack for natural beauty. But I think it's fair to say that China would beat the US in a contest for the most beautiful and unique natural scenery. After all, only China has a Tibet. One type of landscape that is unique in China is agricultural landscapes. Fields carved into mountains (terraces), valleys dotted with traditional villages. Farmland in the US is flat and monotonous. The Chinese countryside is much more picturesque.
2) Safety. I can walk down a dark street at night in any Chinese city and not worry for my safety. Unfortunately, that is not true in the United States. China has much less violent crime than the US. China also has fewer guns
3) Environmental impact. Things are getting worse, but the fact remains, per capita use of energy and resources is still much lower than in the United States. Americans have bigger houses, bigger cars, they drive more, and they waste more. Chinese style apartments, urban densities, and public transportation make for a much smaller per capita footprint. The Chinese government is also doing more than the US to develop new and better alternative energies.
4) Public transportation. Both urban transportation (subways, buses) and long distance transportation. China's railway network is much, much better than the US' pitiful Amtrak system. On top of that China has the world's best high speed rail network, and it's expanding every year. Even in rural Yunnan province the public transportation network is amazing. I can go anywhere on a public bus. You cannot do that in the United States.
5) City life. There's so much more activity in Chinese cities. Everywhere you go there are people doing things, playing, selling things, buying things. You might think this is a bad thing, but I think it's a good thing. People out there interacting with other people. It's a good feeling. We need more of this feeling in America. I really like the street vendors and the sellers in the markets. Not just big cities, either, but small towns, too.
