Origin Story
东汉光武帝刘秀统一全国后，天下基本安定，但还有西州隗嚣和蜀地公孙述割据一方。大臣们纷纷进言讨伐，但光武帝却说："且当置此两子于度外耳！" 他认为隗嚣和公孙述的势力不足为虑，不会影响到他的统治，于是把心思放在巩固政权和发展经济上。事实证明，光武帝的策略是正确的，他最终平定了天下，建立了强大的东汉王朝。这个故事告诉我们，有些事情虽然表面上看起来很重要，但如果不会对大局产生实质性影响，就可以暂时搁置，集中精力处理更重要的事情。这体现了光武帝的战略眼光和决断能力，也体现了置之度外是一种战略性的选择，而非简单的忽视。
After Emperor Guangwu of the Eastern Han Dynasty unified China, the country was basically stable, but Kuyin of Xizhou and Gongsun Shu of Shu still held separate territories. Ministers repeatedly urged him to launch attacks, but the Emperor said: "Let's put these two aside for now!" He considered their forces negligible and would not affect his rule, so he focused his efforts on consolidating power and developing the economy. History proved the Emperor's strategy correct. He finally pacified the country and established the powerful Eastern Han Dynasty. This story teaches us that some things, though seemingly important on the surface, can be temporarily set aside if they do not have a substantial impact on the overall situation, allowing one to concentrate on more important matters. It highlights Emperor Guangwu's strategic vision and decisiveness and shows that setting aside problems is a strategic choice, not simple negligence.
