Sanming City, Fujian Province is an immigrant city, right? The best information is available.

This is an immigrant city. In the past, there were many Fujian people in Shanghai, and there were also local people in Sanming. I was born and raised there, and the air is average, because Sanming is a heavy industrial city, but now the industry is slowly moving to Shaxian, so it is better. There have been more foreigners in the past two years, and I feel worse than before. However, the law and order in Sanming is really good, and there are almost no robberies and murders.
