More information and sources can be found within this book. However, here are a couple other links to reputable sources. Apologies for formatting, it's a bit weird.

• Man-made famine of Ukraine and political executions

• And some more info

• and even more

• You could also look into the 1 million people he killed as "enemies of the state"

• while not exactly a genocide, he ordered his men to kill fellow soldiers. There are a ton of articles on this if your want to search for more.

I haven't addressed my comments on Mao, but simply put, it's the same regime that committed the Tieneman square massacre and covered it up. For more current options, you could look into how they literally bolted doors on apartments to keep them in during COVID-19, put barbed wire in staircases, lied about infectivity rates, and cut off research discussion to the world. For non COVID-19 topics, they are currently running a genocide on Uyghur Muslims (plenty of links online), plenty of human rights violations, and more here.

Total media control keeps everyone in line when they can only see the good that happens in their country. They don't know about any of the above, it's all hidden from them.
