A Chinese Wonder Book. Norman Hinsdale Pitman

a tale that has been repeated a million times by poets, story-tellers and devoted mothers, for you must know that on this third casting, when the earthen mould was removed, there stood revealed the most beautiful bell that eye had ever looked upon, and when it was swung up into the bell-tower there was immense rejoicing among the people. The silver and the gold and the iron and the brass, held together by the blood of the virgin, had blended perfectly, and the clear voice of the monster bell rang out over the great city, sounding a deeper, richer melody than that of any other bell within the limits of the Middle Kingdom, or, for that matter, of all the world. And, strange to say, even yet the deep-voiced colossus seems to cry out the name of the maiden who gave herself a living sacrifice, "Ko-ai! Ko-ai! Ko-ai!" so that all the people may remember her deed of virtue ten thousand years ago. And between the mellow peals of music there often seems to come a plaintive whisper that may be heard only by those standing near, "Hsieh! hsieh"—the Chinese word for slipper. "Alas!" say all who hear it, "Ko-ai is crying for her slipper. Poor little Ko-ai!"

      And now, my dear children, this tale is almost finished, but there is still one thing you must by no means fail to remember. By order of the Emperor, the face of the great bell was graven with precious sayings from the classics, that even in its moments of silence the bell might teach lessons of virtue to the people.

      "Behold," said Yung-lo, as he stood beside the grief-stricken father, "amongst all yonder texts of wisdom, the priceless sayings of our honoured sages, there is none that can teach to my children so sweet a lesson of filial love and devotion as that one last act of your devoted daughter. For though she died to save you, her deed will still be sung and extolled by my people when you are passed away, yea, even when the bell itself has crumbled into ruins."
