It sounds to me that Chuang Tzu's description of true men is the description of Jesus or
St Francis of Assisi or some true saints, or enlightened human beings such as Buddha and all.

We ordinary human beings can only dream of such attainment or such state, yet perhaps we should all try for our own sake.
This is from the book, "The Way Of Chuang Tzu" by Thomas Merton, who was a catholic priest monk and a serious student of Taoism.

"The classic period of Chinese philosophy covers about three hundred years,
from 550 to 250 B.C. 
Chuang Tzu, the greatest of the Taoist writers whose historical existence can be verified (we cannot be sure of Lao Tzu), flourished toward the end of this period, ...."

...from the introduction of the book

 Chuang Tzu (莊子) is believed to lived in the Fourth or Third Century BCE, at a time when China was split up into a number of states weakly held together by the Chou dynasty. He was a minor government official for a while and was offered higher office, but declined on the grounds that it would limit his freedom.

 

    His thought is contained in the 33 chapters that remain of the Chuang Tzu, which describes both his philosophy and his way of life. In it, Chuang Tzu enlarges on the teachings of Lao Tzu in a lively Taoist discourse that opposes the ideas of Confucius and Mo Tzu. These philosophers argued for particular ways for improving the condition of man, each contradicting the other. Chuang Tzu argued that the processes of nature unify all things, so that humanity should seek to live at one with nature and not impose upon it.
He concluded that one could do more by doing nothing.

 

    Chuang Tzu viewed nature as having great spontaneity and change, with all things—large and small, beautiful and ugly—equally important and ever in a constant flux. In this way, he enlarged the notion of the co-dependence of things, one causing change in another, which appears in Buddha’s thought. Chuang Tzu also emphasized the mutual causation of opposites: for example, that life leads to death. His dislike of formal structures lead him to put forward his ideas in imaginary dialogues.
