许多人以为北京的钟楼和鼓楼里面只有一钟、一鼓。其实,过去鼓楼一共有25面鼓,其中有1面“主鼓”,24面“群鼓”。主鼓高达2米多,直径也有1.4米,是用整张牛皮蒙制的。钟楼倒是只有1口钟,不过早先是一口铁钟,现存的铜钟铸于明永乐年间,钟体高5米以上,3个人合抱都很困难,重达63吨,堪称中国古钟之最。 Many people think that there is only one clock and one drum in the belfry and dinning hall in Beijing. In fact, in the past, Drum Tower had a total of 25 drums, including one “main drum” and 24 “drums.” The main drum is more than 2 meters high and has a diameter of 1.4 meters. It is made of whole cow hide. The clock tower was only one bell, but earlier it was an iron bell. The existing bronze bell was cast in the Ming Yongle era. The bell body was more than 5 meters high. It was very difficult for three people to hold each other and weighed 63 tons. It was the most ancient bell in China.
