In the Song Dynasty, General Liu Ping fell in battle. Many blamed the eunuch supervisors for interfering with military command. The emperor wanted to remove all eunuch overseers, but Chancellor Lü Yijian advised a different approach.
He suggested that the chief eunuch himself recommend candidates for the posts—and be held equally accountable if they failed. The next day, the chief eunuch begged the emperor to abolish the entire system.
Lü did not fight the system directly. He created conditions that made it collapse under its own weight.
True wisdom lies not in confrontation, but in guiding others to see for themselves. When you stop forcing change, change often comes more naturally. Like water shaping stone, the quietest force is often the most powerful.
