How many people has the Chinese Communist Party killed?

According to The Nine Commentaries the Party has killed about 80 million Chinese people since it came to power about 80 years ago. It is more then all of the World War's causalities put all together. I am not sure if you remember (Don't know how old you are) but the Mao wanted the opinion of scholars and scientists view of how to make the party stronger. In the end he deemed them "counter revolutionary" and had all 20,000 of them killed. Also not to mention how many died of the tiananmen square massacre and famines, people in every kind of religion in China, monks, Falun gong, ect. Point being the CCP is No good.
