LOL!... You are so fucking dumb and stupid. The Chinese themselves were also selling opium to their own people. They were buying from angmoh suppliers dirt cheap if not, they would have to buy it from Yunnan tribes from the mountain.
Also, if idiot Ming Emperor and their dumb fucks were smart, they could have rule the world instead of having dumb fuck Muslim eunuch go sight seeing wasting money and retard Qing emperor rejecting technology when he was given a chance to follow like how Japan became industrialized. Also, Qing are Manchu foreigners and not han Chinese, you dumb fuck!
Go on, continue to tell us how dumb and stupid you are. LOL!...
