Origin Story
深山老林里住着一位隐士，他与世隔绝，终日潜心修道。一日，村里来了位县令，想拜访这位名声远扬的隐士。他带着随从，一路跋山涉水，终于来到隐士的茅屋前。县令敲了敲门，屋内却没有任何回应。他再次敲门，依然静悄悄的。县令耐着性子，又敲了几遍，屋里才传来了轻轻的脚步声，门缓缓打开，隐士站在门口，目光平静，默不作声。县令见此情景，也不好意思多说什么，只是简单地说明来意，便告辞离开了。隐士默默地关上门，继续他的修道生活，对尘世的一切都默不作声。
A hermit lived in a remote forest, cut off from the world and devoted to his meditation. One day, a county magistrate came to visit this far-famed hermit. With his attendants, he traversed mountains and rivers, finally arriving at the hermit's thatched hut. The magistrate knocked on the door, but there was no response. He knocked again, still silence. Patiently, the magistrate knocked several more times, before the sound of gentle footsteps came from inside, and the door slowly opened, revealing the hermit standing in the doorway, his gaze calm and silent.
