Only a Great Leap Forward itself had caused 20-30 million of deaths (the Chinese famine 1958-1961).
There were people argued that the Chinese famine was caused by natural disaster; but believed me, it was the great leap forward which made this happened! It was Mao Zedong’s nonsense which caused misery throughout China. Not to mention there’re still many other ridiculous things, such as the Cultural Revolution, the Anti-Righist campaign,etc. Honestly, by reading texts and papers about Mao and that time period, I couldn’t find much 功 of Mao. His arrogance and ignorance had brought tremendous tragedies to China!
Through all campaigns (land reform, GLF, Cultural revolution anti-right, etc), Mao, as a mad man, drove China further into poverty and dehumanization.
I remember the English Ambassador being quoted saying in the well-known memoir of Mao’s doctor that Mao was a devil. The sad thing is that the Communist party will never allow its people to know the truth about Mao, not alone to learn from all the mistakes.
The first sign of democracy is that that Mao’s protrait will be taken down in the Tianmen Square. But, will I see that one day?
