@corditeman: Geographical/geological changes go in ASB.
As for myself...what about the Empress Dowager Cixi dying considerably earlier than OTL? IOTL, she served as a considerable block on the ability of the late Qing to reform and modernize China, even going so far as to overthrow the Guangxu Emperor when he instituted a series of reforms. She bears a lot of responsibility for the later ills China has suffered. So, what if, before she could do all that (say, sometime in the 1870s or 1880s) she died somehow?
