Domestic margin financing and securities lending is a characteristic of China, and how to play it depends on the policy (that is, whether to use margin financing and securities lending is up to the state, and considering that the use of margin financing and securities lending will increase the risk of investors, the state may not consider it at first, or control it in proportion).

Then what you said should be replaced by margin short selling, that is, short selling mechanism, but only some stocks, similar to Hong Kong, can not be short-selling like all US stocks. You should know that the US stock market mainly depends on the market maker system, and the current supervision mechanism in China can't achieve this.
