I suggest you not to speculate in foreign exchange. The risk is too high. In addition, it is illegal in China at present. In fact, doing foreign exchange is nothing more than buying and selling. If this is the case, I still suggest that you open a Hong Kong stock account in China to buy and sell Hong Kong financial products. This is more formal. At present, there are Guoyuan, Shen Yin Wanguo and other brokers who can open Hong Kong stocks in China and are also working hard on this procedure.
