In China there is also a widespread theory that walking backwards and shouting out loud in a specific way is highly beneficial for ones health. My own grandpa is doing it regularly. This theory is widespread mainly in all the Asian communist counties. Indeed, I have been to China, Laos and Vietnam and I confirm that there are a few very similar habits and characters of their society that I ascribe to them being communist. The old people, especially women, all gather in parks and dance hilarious dances every night with horrendous music. But it is sort of cute in its own way. Then, a lot of males spit everywhere. Males may often display their giant and rather ugly belly by pushing up their T shirt on top of their belly. So you see them half naked on the top but they don't take the T shirt down. They wrap around their controllers for TV in plastic bags, they boil water to drink, they have no concept of queueing, manners are all gone, rude behaviour in the eyes of Western people. But they are usually very nice and helpful if it comes to it, friendly to foreigners with a sort of admiration, hospitable, and easy going. It is very cheap to travel in communist countries and you will have a hard time buying private properties there. Thats sort of my intake of the commonalities of communist countries. Very curious and very similar. I wonder how it used to be in the Soviet Union.
