2. What's the point? 【wòxn cháng dǎn】？

Interpretation: The State of Yue was defeated by the State of Wu, and Gou Jian, the king of Yue, was determined to take revenge. It is said that he sleeps on firewood and tastes gall before eating and sleeping to encourage himself not to forget his shame. After a long period of preparation, the State of Wu was finally defeated (historical records show that Gou Jian's family had only courage, while Su Shi's Sun Quan's Answer to Cao Cao had only courage). Describe a person who works hard and is determined to avenge his country.

Language: "Sun Quan intends to answer Cao Cao's book": "My servant was sent; Stand still; Mourn for the sun and the moon and sigh for fame. "
