What do you mean by chaos? In other words, what is chaos?
If you are talking about poor social atmosphere, it is everywhere, and there are still chaotic places in Beijing and Shanghai!
I am a native of Lincang. I have lived for more than 20 years, and I think I am good. Fighting, murder and arson are still out there somewhere! This is not unusual!
Just because you're close to drug dealers doesn't mean drugs are all on the street! Of course, be careful when you go out alone at night, and don't go to remote and dark paths.
No matter whether others are chaotic or not, as long as you are honest and trustworthy and do business separately, who will be chaotic with you? Yes!
We Lincang people are just too honest, and all the money has been earned by you foreigners!
