Story:
During the Warring States period, King Xiaocheng of Zhao was not a capable ruler. He was autocratic and often prioritized small gains, leading to significant losses.
When a conflict arose between the state of Yan and Zhao, Yan appointed General Gaoyang to lead an army of 100,000 to attack Zhao. King Xiaocheng of Zhao, believing his own state lacked strong generals, offered 50 cities to the state of Qi in exchange for General Tian Dan's assistance.
Lord Mafu, observing this, indignantly told Lord Pingyuan that King Zhao was making a mountain out of a molehill.
