Float like a butterfly

You may have heard of time juggling or dream in a dream in the movie Inception, but do you know the Taoist philosopher Zhuangzi (3rd century B.C.) also touched the definitions of reality vs. illusion in his dream? 

You may have read about Shakespeare’s Romeo and Juliet, but do you know there’s almost a Chinese equivalence to that, which has also inspired one of the most famous orchestra music works appealing to western ears?

These all have something to do with one insect – butterfly.
