|In 1941 Mao forgot when the CPC was founded and chose the date instead|
|The actual date is July 21, 1921 in Shanghai in this building|
|Even Hu Jintao propagated the date of July 1 in 2011|
So if you hear or read the Communist Party of China was founded on July 1, 1921, it's factually wrong. Yes, Mao was wrong.
And no one was brave enough to correct him or successive leaders...
