Liang Baobao, a woodcarving craftsman from Tianshui, Gansu: 56 years of inheritance and display of Fuxi hexagrams. He has been obsessed with wood carving for most of his life.

"Wood, like people, has habits. No matter how long it takes, it must be allowed to have its'strength' gone, in order to avoid fission caused by thermal expansion and contraction, and the object can be long-lasting and durable," he said. The pear and walnut wood he is using now takes about one and a half years from "strengthening" the wood to the actual completion.
