History's most 'badassed' history teacher

I have just discovered the history lectures of Yuan Tengfei (袁腾飞), history's most 'badassed' history teacher (h/t to Tang Buxi of Foolsmountain for the translation of '牛') via Danwei. It's well worth taking a look at his archive if you can speak Chinese, if not Danwei has a subtitled version of one of his speeches.
