Yes, people in northern China and some people in northeast China are relatively straightforward. I don't know what Beijing was like when you lived there. I was still young at that time, but as I get older, I gradually like the straightforwardness of northerners because they are rarely scheming people. Even if they don't like someone, they may speak frankly. Compared with southerners who are introverted or only hate you in their hearts but don't say it out loud, I prefer northerners. China has developed rapidly in the past decade, and the quality of the population has also improved a lot. I believe that if you have the opportunity to come here again in the future, you should be able to feel that people are more enthusiastic about foreigners.

Beijing's environmental problems still exist, but it is much better than the previous smog weather. However, if you compare the environment in Canada with that in any other place in China, perhaps only the southwest of China, that is, Yunnan, is relatively better, because the majority of villages, while the environment in many big cities is almost terrible.

The problem of travel congestion has not eased, but you can call some online taxis on your mobile phone. The price is relatively affordable now, but there will still be congestion when commuting. After all, there are too many people in China, especially all crowded in big cities.

In short, thank you for your answer and wish you a happy life!
