During the Warring States period, a butcher named Pao Ding was renowned for his extraordinary skill in dismembering oxen. When Lord Wenhui of Wei watched him work, he marveled, "How have you achieved such perfection?" Pao Ding replied, "I follow the natural grain of the ox, guiding my blade through the spaces between joints, never hacking at bone. A good butcher changes his knife every year, but I have used the same blade for nineteen years, still sharp as if fresh from the whetstone." Lord Wenhui exclaimed, "Excellent! From your words, I have learned the art of nurturing life." This story illustrates the principle of aligning with nature's patterns to achieve effortless mastery.
Once, the cook Ding was specially summoned to perform his butchering skills for King Hui of Liang. With a gleaming knife in hand, he set to work without a moment's hesitation. He touched the ox with his hand, leaned on it with his shoulder, stepped on it with his foot, and pressed his knee against it, the sounds of hide and bone separating following the blade's movement; as he drove the knife deeper into the ox's body, even louder sounds arose. In short, all his movements perfectly matched the rhythm and melody of the *Sanglin* dance, and the various sounds made by his knife were as rhythmic as the *Jingshou* melody.
In no time at all, the butcher Ding had completely dismembered an ox. King Hui of Liang exclaimed, "Excellent! How did your skill reach such a remarkable level?" Butcher Ding set down his knife and calmly replied, "What I follow is the Way, which goes beyond mere skill. When I first began cutting up oxen, I saw nothing but the whole ox. After three years, I no longer saw the whole ox." The king asked, puzzled, "If you no longer see the whole ox, wouldn't that make it even harder to know where to insert the knife?"
Pao Ding shook his head and replied, "That is not what I mean. What I am saying is that by now I have a complete understanding of every gap and joint in the ox's body, so when I look at it, I no longer see a whole ox but the many parts that can be separated. When I butcher the ox, I connect with it through my spirit rather than using my eyes, and I know exactly where to place the knife. I follow the ox's natural structure, cutting through the spaces between the muscles and tendons, and then moving along the gaps between the joints, working according to its inherent design. I do not even encounter these minor obstacles, so how could I ever hit a large bone?"
King Hui of Liang, intrigued, asked further, "To act like this, should the knife be sharpened quickly, or replaced often?"
Cook Ding shook his head again and said, "A more skilled cook changes his knife once a year, because he uses it to cut meat, not to dissect an ox. An ordinary cook changes his knife every month, because he uses it to hack at bones."
King Hui of Liang asked, "Then how often do you change your knife, a cook like you?"
Pao Ding picked up his knife, pointed at it, and said, "I have used this knife for nineteen years, carving up thousands of oxen. But look, Your Majesty, its blade is still as sharp as if freshly honed on a whetstone."
“What is the reason for this?” King Hui of Liang asked eagerly.
The cook explained, 'It's simple: a cow's joints have gaps, while my blade is so thin it barely has any thickness. Inserting an ultra-thin blade into those gaps leaves plenty of room to maneuver. That's why, after nineteen years, my knife remains as sharp as if fresh from the whetstone. Still, whenever I encounter a tangled sinew or tricky spot, I proceed with utmost care, focus completely, slow my movements, and guide the blade gently. Only then do I hear the flesh separate from the bone, and the carcass falls apart like clumps of earth. At that moment, I feel true satisfaction, wipe the blade clean, and put it away in its sheath.'
King Hui of Liang remarked with emotion, "After listening to Cook Ding's words, I have come to understand the principles of nurturing life." The idiom "Cook Ding Carving the Ox" is used as a metaphor for mastering the patterns of something, thereby handling tasks with ease and skill.
