About China, I am not sure about the stability of its power. As it gets money from exportation, covid impacted it a lot, as we reduced our consumption. It is one of the country that is the more subject to globalization habit changes.

For masks, I see people making no effort while wearing them. At the start, we need "1" or "2 meter" distance between people. Now they have the mask, 30cm away is perfectly fine. I wonder which option is the best.
