As we all know, eggshells are fragile, so that few people will associate it with carving. But artists have broken the taboo, carving intricate pictures on eggshells.

A dozen complex processes can shape a piece of eggshell work. There are more than 10 different carving methods and themes can be all-encompassing, including figures, landscapes, animals and poems.

As an eggshell is thinner than 1 millimeter and a minor mistake will waste all previous effort, the final products all deserve to be "one out of a hundred".
