Question

What caused China to stay isolated for so many years?

Answer 1

The large land was isolated from much of the rest of the world by dry deserts to the north and west, the Pacific Ocean to the east, and impassable mountains to the south. This enabled the Chinese to develop independently from other world civilizations.

Answer 2

the other answer that said d is wrong , it is a) the natural barriers.
