Origin Story
话说东汉末年，神医华佗医术精湛，名扬天下。有一次，两位官员倪寻和李延同时患病，症状都是头痛发热。华佗仔细检查后，发现两人虽然症状相同，但病因却不同，倪寻是外感风寒，李延是内火旺盛。于是华佗分别为他们开了药方，一个以泻火为主，一个以散寒为主。第二天，两人都痊愈了。这个故事说明，治病要对症下药，才能取得好的效果，处理问题也一样，要找到问题的根源，才能有效解决。
It is said that during the late Eastern Han Dynasty, Hua Tuo, a renowned physician, was famous throughout the land for his superb medical skills. Once, two officials, Ni Xun and Li Yan, fell ill simultaneously, both suffering from headaches and fever. After a careful examination, Hua Tuo discovered that while their symptoms were identical, their underlying causes differed. Ni Xun had contracted a common cold, while Li Yan suffered from excessive internal heat. Hua Tuo accordingly prescribed different remedies for each, one focused on dispelling heat, the other on relieving cold. The next day, both were fully recovered. This story illustrates that effective treatment requires addressing the root cause of the illness; similarly, solving problems demands identifying their origins for an effective resolution.
Usage
通常用于比喻解决问题的方法要针对问题本身，要找到问题的根源，才能有效解决。
