He learned much about the philosophers of his time but choose Lao-tzu as his master. This is why he dedicated most of his homonymous book
to the ideas of Lao Tzu which he illustrated in a methaphorircal form.
He was also a critic of Confucius. "Chuang was an admirable writer and skillful composer - wrote Ssu-ma Ch'ien - and by his instances and

The Butterfly Dream is the most quoted and commented parables of Master Chuang. Here's the English version by James Legge:
Once upon a time, I, Chuang Tzu, dreamt I was a butterfly, fluttering hither and thither, to all intents and purposes a butterfly. I was conscious only of my happiness as a butterfly,
unaware that I was Chuang Tzu. Soon I awakened, and there I was, veritably myself again. Now I do not know whether I was then a man dreaming I was a butterfly, or whether I am now a
butterfly, dreaming I am a man. Between a man and a butterfly there is necessarily a distinction. The transition is called the transformation of material things. (Book II, chapter 13).
The transformation of things explains why one can be both a butterfly and a man, without having to lose his continuity. Though Legge thinks this is a hint to the Buddhist maya
(illusion), I think this is rather a pleading for the principle of continuity of consciousness.
