Right. The Chinese government does not trust the electronic money market. Electronic money can affect the national currency system. Investing in e-money will be a big risk. So they should buy gold and silver.
China does so as a safeguard for their country. And they always have the idea of buying all the other countries' materials for their country. After all these countries run out of natural resources will have to buy the Chinese at a very expensive price. With gold and silver, they think so and it is a rare item for life.
