I may not give you objective advice, but I think it's worth a visit. Ningxia has developed rapidly in recent years, and promising groups and companies like Ning Mei have emerged. First, it is developed, but it is not very bad. Second, there are more coal being mined or not yet mined in Ningxia, which has more prospects for the coal industry. Ning Mei is one of the best enterprises in Ningxia, so you'd better contact the company for details.
