Wisdom cannot leave the wisdom of learning without learning. It's floating light, soap bubbles, floating light, fleeting, rising and disappearing instantly.

Wisdom from learning is a searchlight and a fortune.

The spring water of Zhuquan is the most reliable, clearest and most precious.

(Comparative argument, figurative argument)

We need wisdom to cover, see and use knowledge (metaphorical argument)

After-class notes

Work as skillfully as a skilled butcher cuts the carcass of a cow-do sth very skillfully/professionally.

-"Zhuangzi Health Master"

My skillful hands, shoulders, feet, knees, knives and tenors are all classic first encounters. Wen said, "Hey, good! So far? " My master let go of his knife and said to him, "I am a good minister and I am proficient in technology." When the first minister solved the cow, he saw nothing but the cow; I haven't seen all the cows for three years. At this time, I met God, not with my eyes, but with Zhi Zhi's desire to do things. According to heaven, I criticize the big gap and the big difference. Because its courses, techniques and skills are not bad, but the situation is great. A good man is a better cutter; There are many knives and many folds in the family month. Today, I killed thousands of cows with my sword for nineteen years, but if the blade is new. There is a gap between people for a while, but the blade is not thick; Without thickness, there is room, and there is room for recovery. 19 years, the blade is new. Although as for the clan, I find it difficult, so I took a warning and stopped watching it. Slow action; The knife is very small, and what should be solved has been solved, such as land. Stand with a knife, look around, aim high, and hide it with a knife. " Wen said, "Good! I listened to my master and I have to stay healthy. " ("Zhuangzi Health Master")

Liang saw my master chopping cattle, but seeing that his hands were fast and good, he repeatedly praised his skill. My master replied, "I can do this mainly because I am familiar with all the physiological structures of cattle." At first, I saw a whole cow; Now, I don't see a whole cow. Where are the joints? Where are the meridians? Where to operate? How much strength does it take? Everyone knows what to do. So, although I used this knife for 19 years, I dissected thousands of cows. But it is as sharp as a new knife. . "

Liang said, "Good! I learned the truth of keeping in good health from my words. "

[Analysis] This story tells us that to do any kind of work, we must clearly understand the law. Only by mastering the objective laws can the work be done well. Because I am familiar with the physiological structure of cattle and understand the laws of cattle, it is very handy to kill cattle. Understanding objective laws requires a practical process. If you don't start to understand cattle, you will never understand their physiological structure.
