Lord Mengchang was a 3rd-century BC Chinese nobleman famous for maintaining a household of three thousand retainers and scholars. Think of it as an ancient think tank mixed with a social club. He welcomed anyone with talent, no matter how humble their background.
His most famous story involves a daring escape from the Qin kingdom, where he was held prisoner. Among his retainers was a man who could perfectly imitate a rooster's crow and another skilled at picking locks — hardly prestigious talents. Yet when Mengchang needed to escape at dawn, the lock-picker opened the gates while the rooster-imitator fooled the guards into thinking sunrise had arrived.
The moral became legendary in Chinese culture: every person has hidden value, and true leadership means recognizing potential in unexpected places. Mengchang's willingness to invest in diverse talents, including those others dismissed, ultimately saved his life and secured his legacy.
