Zhuge Zhan
The Shu general Zhuge Zhan led an army from Fu County to Mianzhu, where they engaged Deng Ai and his troops in battle. Deng Ai ordered his son Deng Zhong () to flank the enemy from the right, and Shi Zuan () to flank the enemy from the left. Both Deng Zhong and Shi Zuan were driven back by Zhuge Zhan, and they told Deng Ai: "The enemy cannot be defeated.". Deng Ai sternly replied: "This battle will determine whether we live or die. What do you mean when you say the enemy cannot be defeated?" He wanted to execute them, but they turned back and hastily readied their troops for battle again. They defeated the Shu forces and killed the enemy officers Zhuge Zhan, Zhuge Shang and Zhang Zun.
