Story:
During the Eastern Han Dynasty, a scholar named Yu Xu was invited by Grand Commandant Li Xiu to serve as an official.
When the Western Qiang suddenly invaded, Yu Xu had disagreements with General Deng Zhi regarding military strategy, which led to conflicts.
Later, Deng Zhi found an opportunity for revenge and transferred Yu Xu to serve in Chaoge.
However, Yu Xu viewed this as a positive development, believing that just as one should choose to cut down trees with deeply entrenched roots and gnarled branches to truly demonstrate the sharpness of an axe, he welcomed challenging tasks.
