"Nang Yingxue works hard, hangs his head and studies hard, wait until the day when he wins the championship, and then discuss the victory or defeat with Er Cao." What does it mean?

It is said that in ancient times there was a scholar named Chi Zhiwu who only paid attention to reading with his heart and did not pay attention to protecting his eyes. At that time, humans had not yet invented glasses. After Chi Zhiwu became highly myopic, he could only rely on adjusting the distance to see objects clearly.

So people made up a joke to ridicule him: "It's strange, it's strange, it's really strange. The locks locked the eyelids. If I had listened to others' advice, how could I be asking for trouble now!" Chi Zhi After hearing this, Wu still persisted and wrote a poem in reply to those who laughed at him: "Nang Ying Ying Xue works hard, hangs on the beam and stabs the buttocks to study hard, wait until the day of winning the competition, and then discuss the victory or defeat with Er Cao!"

After some time, the day of the competition arrived, but the ambitious Chi Zhiwu was unable to take the exam because he could not see the test questions clearly. Chi Zhiyu regretted it so much that he wrote a poem to warn future generations. The poem says: "If I had known that I would be blind today, why would I have bothered to study hard? I advise all the people in the world not to learn from Chi Zhiwu." The enlightenment of Chi Zhiwu's story is that only focusing on learning and ignoring the body is not only detrimental to subsequent development, but also harmful to the health of the body. The current developments are equally unhelpful.
