Is there a stock exchange market in Macheng City, Hubei Province?

Yes, you can open an account in a branch of Agricultural Bank of China (changjiang securities). This is the easiest way, and the handling fee is only 2‰. You can also open an account in Huatai Securities (just opposite the old education building in Macheng City, there is a credit cooperative, near Macheng Shopping Mall), but it is very troublesome and the handling fee is 3‰ higher.
