You need to be a scientist to fully understand the nature of these calcareous formations carved in the rock by water; but anyone can admire the soectacular landscapes they provide. This is what China has for us to marvel at. This is a country which, according to experts, is home to half of the world's emerged calcareous rocks.展开更多
