The kings of Qin and Zhao met at Mianchi in 279 BC to forge an alliance. During the banquet the King of Qin slyly invited the King of Zhao to play the zither. At this the Qin official historian gleefully wrote down: "The King of Qin commanded the King of Zhao to play the zither."
當年秦王與趙王在黽池相會，宴會上秦王故意請趙王彈瑟，秦國管歷史的御史馬上得意地記下：「某年某日秦王命趙王鼓瑟。」
