What geographical features protected china from invaders?

Well the thing that protected inner china was the great wall In the west, there was the Gobi desert, malayas in the south and there was a sea in the east.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
