Buy the country a handover? Or buy the United States a handover?

Yesterday, the village chief banned overseas brokerage firms from opening accounts and depositing funds for mainland Chinese to trade Hong Kong and US stocks, which is essentially calling on everyone not to take over American technology, but to support domestic tech stocks.
This timing interrupts the flow of domestic funds to the United States, and the timing is very delicate.
There are three US trillion-dollar giants planning to go public, including Elon Musk's SpaceX, Sam Altman's OpenAI, and the currently popular Anthropic. These are all giants in the American tech industry, and the future of artificial intelligence has many fans in China.
China also has two tech giants planning to go public, one is Hefei State-owned Changxin Storage, led by local state-owned assets, and the other is Wuhan State-owned Yangtze Memory, also backed by a national fund. Both have the potential to surpass one trillion yuan in market value.
So, at this critical moment, as a Chinese retail investor, is it to support domestic tech giants or to support American AI giants? This has become a choice.
Now, it's no longer a choice; the way out has been blocked, and domestic retail investors no longer have the opportunity to support the US.
Two domestic storage companies, leaders in domestic chip replacement, perhaps in the next five to ten years, retail investors who support them will thank the village chief for the choice he made.
