Apparently no Covid immunity either. I'd mutiny over the lack of immunity.
I’d just suggest you simply not go there.
There are lots of nice pictures on the Internet of the Great Wall, Forbidden City, and other fascinating things created in the days when China was Free.
(After all - walls ‘don’t work’, despite the fact that we’ve got our own ‘Wall’ and ‘Forbidden City’ in DC, now.
These days, you don’t even have to leave your home country to experience all of the same exoticism that Red China provides.)
