Can someone give me a link to a map of China?

I am looking for an old map of china. I learned today in class that back in Imperial China (I think or the republic era) cartographers used to make China look like an island. I have tried looking for one but I am having a hard time finding it.
Update: I need a map of China that shows china as a seperate piece of land, like an island. This is the way cartographers in China made maps back in the day apperently. My teaher attributes that to the fact that they thought they were the center of the earth
