Please explain to me how its projection. Modern China's problem is the abundance of uneducated people. The racism mostly stemmed from ignorance. Same exact reason that when I visited Ecuador people pointed and stared.

The wiki article doesn't even state that 'Han chauvinism' was 'bad'. It doesn't list a single incident of 'Han chauvisnism'. Do you know what the little red book is? You took the first result from google search and you didn't even read it.
