Origin Story
从前，在一个小山村里，住着一位名叫“神医”的老者。他医术高超的名声远扬，吸引着四面八方的病人前来求医。然而，老者年事已高，医术早已不如年轻时精湛。他经常将一些简单的药方反复使用，甚至有些病人病情加重，老者却只是摇头叹息。许多人开始质疑他的医术，说他徒有其名。但老者还是固执地坚持着，对外宣称自己是神医，直到有一天，一位年轻有为的医生来到村中，凭借真正的医术治好了许多病人，老者“神医”的名号才彻底被打破。从此，人们才明白，真正的医术不是靠虚名得来的，而是靠精湛的技术和对病人的真诚。
Once upon a time, in a small mountain village, there lived an old man known as the "divine doctor." His reputation for superb medical skills spread far and wide, attracting patients from all over. However, the old man was advanced in years, and his medical skills were no longer as refined as they once were. He often used the same simple prescriptions repeatedly, and some patients' conditions even worsened, but the old man would only shake his head and sigh. Many people began to question his skills, saying he was only a name. Yet, the old man stubbornly persisted, proclaiming himself a divine doctor, until one day, a young and capable doctor came to the village. With his true medical skill, he cured many patients, and the old man's reputation as a "divine doctor" was finally shattered. From then on, people understood that true medical skill is not achieved through empty fame, but rather through superior techniques and genuine care for patients.
