Wha I know about china?

Well I know that they speak mandarin chinese, but many other regional varieties are spoken.  There is technically 2 chinas currently. One the peoples republic of China and the other one the Republic of China which is reduced to only Taiwan. They had a civil war so they broke up from 1 republic into 2 different ones.  They have been rule by emperors until 1901 I believe when the republic was established!
