what exactly do you need to know about kanmen? As far as I know, Kanmen is not very good. As the one above said, the industry is relatively developed, but the environment is very poor. Yuhuan is often short of water. And the integrity of some people over there seems to be not very high. I have done business with people there before, and in the end, there was a phenomenon of default, and finally I had to resort to legal means. In short, I just don't like Yuhuan people very much.
