Li Nanen comes from a small town and she has loved traditional Chinese culture since she was a child. After graduating from university, she studied architecture at the University of Bordeaux, France, and accidentally entered the Advanced Animal Research Society. This research institute is developing a set of ecological building systems called "Sky Garden".
