“九重天”可以说是中国古人最早的天界结构的模型。作品有着繁复的结构和巨大的体量。作晶里总共出现了九种动物,它们相互之间环环相扣,有鸟、人面鸟、人头鸟、羽人、人、老虎、青蛙、娃娃鱼和鱼。九种动物所在的空间各自象征着从“天”到“水”空间递进关系。九种动物互相咬噬,又逐层变大,层层包含。最里层的鸟,嘴里咬着鱼;包着鸟的是人面鸟,在它嘴里面咬着娃娃鱼…… “Nine Heaven ” can be said that the earliest Chinese ancient angels structure model. Works have a complicated structure and huge body. There are altogether nine species of animals in the crystal, interlocking with each other, with birds, nubs, human birds, feathers, humans, tigers, frogs, salamander and fish. The spaces where the nine species of animals each symbolize a progressive relationship from the “heaven” to the “water” space. Nine kinds of animals bite each other, but also layer by layer, layer by layer. The innermost bird bites fish in his mouth; a bird with a bird hugs a salamander in its mouth.
