Origin Story
话说古代某地，一位年轻的官员初入仕途，面对复杂的政务，常常只顾眼前利益，不顾大局。一次，邻国来犯，他只忙着保护自己辖区的安全，却忽略了与其他地区协调合作，导致边境防线出现漏洞，最终导致战败。老官员摇头叹息，说：“此子不识大体，胸无大志！”后来，这位年轻官员因决策失误而被罢官。
Once upon a time, in ancient China, a young official, newly appointed to his post, found himself struggling with complex matters of state. Often, he focused solely on immediate gains, neglecting the broader picture. On one occasion, a neighboring kingdom attacked. The young official, preoccupied with securing only his own district, failed to coordinate with other regions, creating vulnerabilities in the border defenses. This resulted in a devastating defeat. An older, wiser official sighed, “This young man lacks foresight and understanding of the larger issues,” and the young official was eventually dismissed for his poor judgment.
