The expert who knows cattle is an idiom, which originated from Zhuangzi's health preserving master.

My understanding of Niu Pinyin is páo děng Jiěniú, which means that after repeated practice, I have mastered the objective laws of things, and I can do things with ease and use them freely. This idiom is generally used as an object and attribute in sentences, and is often used with "You are comfortable".

This idiom reveals a method of keeping in good health. Zhuangzi used knives to describe people, cows to organize complex society, and knives to explain cows to describe people's social life. Zhuangzi believes that people should find ways to adapt to society and avoid all kinds of contradictions in real life, so as not to be hurt.

This idiom vividly shows that as long as people master objective laws and use them flexibly, they can be liberated from necessity and gain real freedom. We should also pay attention to mastering methods in repeated practice, rather than blindly repeating them.

The origin and appreciation of experts' understanding of cattle;

Master Zhuangzi: "I am a skilled worker who helps writers. Touch of hands, tilt of shoulders, stepping of feet, stepping of knees, sound of knives, tenor.

Wen Huijun praised his skill. My expert explains Dao Yun like this: I have killed thousands of cows in my life, and now I am lucky enough to kill them all, and I have never seen all the cows. If I cut into the cow, I will be able to do it easily. Therefore, although the ox knife has been used for 19 years, its sharpness is still as good as new. "

A clever woman can't cook without rice is a fable of Zhuangzi, a representative of Taoism in the pre-Qin period. The author's original intention is to use it to explain the way of keeping in good health, thus revealing the truth that people should conform to the laws of nature.

The full text can be divided into four paragraphs. In the first paragraph, I wrote about skilled cattle's skilled movements and wonderful sounds. The second paragraph is followed by Wen Huijun's praise, which sets off my master's exquisite skills from the side; The third paragraph is my answer to Wen, mainly about the three stages of my reaching Tao. In the fourth paragraph, Wen Huijun understood the truth of keeping in good health after listening.

The article uses a variety of writing techniques, with rigorous structure and vivid and concise language, which embodies the wanton features of Zhuangzi's Wang Yang.
