Hehe, now the country is also smart. If you are developing these resources, you will eat the old money. Where can I rely on mountains for food and water for food? Now many import and export products are not allowed to be exported, so the price has soared, but the demand has not decreased. On the contrary, due to the reduction of resources, mining will lead to the phenomenon of grabbing resources, so the stock price rose sharply.

Policy reasons and economic interests work together.
