The installation, Wuding (Meaning: No Form or Nothing Lasts Forever), is created by a young artist XuYiyi. 

The underlying idea is that other than the tangible world in front of us, there exists another world. The installation expands man's imagination of space by a seemingly exotic factor, a transmission door, and discusses thepossibility of parallel universe. The periodic reversal of artwork isrelated to a waterfall. By constantly restructure the spatial relationship throughmirrors, the waterfall (or the door) connects two spaces. 

The artist aims to build a connection among passage of time, variation in human mind and change in self-recognition.
