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".
Idiom story
In the crisp autumn season, when the sky is high and the clouds are light, Zhuangzi strolls to the pasture on the north bank of Pushui and sees cows everywhere. He stroked his beard and was intoxicated. Zhuangzi suddenly remembered that my mechanic was going to attend the skill competition today, so he hurried there.
I saw my technical man paying close attention, lifting his breath and abdomen, and he was lucky enough to show his abdomen. He has a dignified expression and is full of energy, waving a knife. The cold light flashed and danced up and down, like lightning splitting into the sky, like thunder stabbing the mountain, and there was a bang, and Daniel fell to the ground.
Look, my palms are here, my shoulders are there, my feet are down, my knees are bent there, and my movements are light and flexible. My master stabbed the butcher knife at the cow, and the sound of peeling meat and bones matched his movements when he lifted the knife, which seemed so harmonious and beautiful.
Just like dancing on the Shang Tang-era music "Sanglin", the sound made when solving cattle is also in tune with Yao Le's "Jingshou". Such a scene is really wonderful. Soon, I heard a loud noise and the whole cow disintegrated.
Wen, who stood by, was shocked. He couldn't help exclaiming loudly, "Oh, it's amazing! How can your skill in slaughtering cattle be so superb? "
When asked, my technical worker quickly put down the butcher knife and said to Liang, "I prefer to explore the laws of things because it is better than ordinary technical skills." When I first learned to slaughter cattle, I saw a huge cow because I didn't understand the body structure of the cow. After three years of experience in slaughtering cattle, I fully understand the structure of cattle. Now that I have slaughtered more cows, I just need to feel them with my heart, not with my eyes. "
"My knife has been used for 19 years, killing more than 1000 cows, but the blade is as sharp as it was just ground on a grindstone." Amid cheers, my master won the championship easily.
