Do you have a source on that? Even if you include landlords killed by the peasantry during land reform, all of the deaths by unintentional famine, and the excesses of the cultural revolution as deliberately killed by Mao, the numbers accepted by Historians are nowhere close to 160 million. This is such a fantastical number that even the famously debunked Black Book of Communism doesn't go over 100 million, and that was including the entire history of the soviet union as well as PRC. The Black Book of Communism famously included both non-births as deaths, and Nazis killed by the Red Army as "victims of communism."
