Rude, obnoxious, disrespectful, uncomplimentary, and vituperative, as he abruptly marches in without warning. Cheng is seen to be arrogant, opprobrious, uncompromising, manipulative, and merciless to Dre, but is happy and friendly with his friends from the dojo. He behaves very violently, uncivilized, uncaring, cruel, and ruthless to Dre and is also very standoffish, hateful, mean, unfriendly, and sadistic. But he was gentle towards you.
