Re: In China
A little before those 5 decades China was extremely poor, strangled economically by the UK with sanctions (which is how the UK got Hongkong) and a dumping ground for british drug pushers who didn't care that their actions and short term greed were destroying a whole society.
Then after the 2nd ww, there were two leaders; one communist, one capitalist and a puppet of the powers that kept China drugged and docile for so long. For some reason the majority of the chinese people rejected the puppet, who fled to an island off the coast called Formosa, now Taiwan.
So. Did you know what happened in the decades before the last 50 years?
I actually highly doubt it. I think you've been taught things similar to 'the US won the 2nd world war (with some minor token help from others).'
