Fun fact: CCP is responsible for far more Chinese deaths than the Japanese invasion and foreign powers during the CCP's precious "Century of Humiliation." Land Reform, Great Leap Forward, Cultural Revolution, Tianamen massacre. And, if Xi starts a war in the SCS or over Taiwan, the amount of blood on the CCP's hands will only grow. It's not foreigners that Chinese have to worry about, but the CCP. Sigh, I can feel the deletion coming...
Land reform wasn't that bloody, especially compared with what the landlords did.
Great Leap forward was caused due to poor governance and natural disasters and even then the worst year of the famine only had 25% higher death rate than India and around the same death rate as pre-revolution China. It only seems so high because China brought death rate down so much after.
Cultural revolution was bad but no where near as bad as some people makes it out to be. The economy did grow at a slower rate but for 95% of people nothing changed in their lives at all.
Tiananmen "massacre" happened because rioters killed soldiers and burned trucks and tanks. Same would have happened everywhere else. Infact all "massacres" that happened in China was done to put down people actively killing innocents.

The worst things people point out about China would be average or even good conditions compared to rest of the developing world lol.
