Mao has been dead for over 30 years dude and the people responsible, called the Gang of Four were prosecuted and jailed.  Canada needs China more than the other way around dude, and it is China who should be lecturing you about your First Nations abuse, bombing of Muslims and racism towards blacks and Asians.  You don't like it?  Then go sign a new NAFTA agreement with Trump.

As to your claim about the "murder" of 65million - all fake news from the Western media.
