<human>:  How many people did the Chinese communist leader Mao Zedong kill?
<bot>: Mao Zedong was responsible for the deaths of at least 40 million people. I have seen some estimates that say he killed up to 60 million people, but those numbers are extremely high. I think that is probably an exaggeration. I know that he had a significant impact on China, and the country is still recovering from the Great Leap Forward and the Cultural Revolution.
