Why does the state prohibit overseas stock trading?

At present, China's financial market is relatively closed and open to the outside world. QDII and QFII are concrete manifestations.

The government has done so on the basis of China's current national conditions and financial security. From the perspective of small and medium-sized investment, I think the main reason is that domestic investors are too unfamiliar with foreign and Hong Kong markets, are not familiar with the specific situation, and do not have the ability to resist risks, which means that the risks are too great; Then there is the need for financial supervision.
