Dog days are coming. Do you know some summer coolers? Watermelon, air conditioner or ice cream? Beverages, fan or mung bean soup?
伏天已至，提到解暑“神器”，你会想到什么？是西瓜、空调、冰激凌？还是饮料、扇子、绿豆汤？
Look, is this an "electric fan" from the Eastern Zhou Dynasty?
快看，这是不是一件从东周时期穿越而来的“小电风扇”？
Don't be "deceived" by its appearance, because it can not help the ancient people cool down a summer.
你可不要被它的外观所“欺骗”，因为它可不能让古人清凉一“夏”。
Actually, this artifact is an imperial bronze bell, usually used as a decoration on carriages during the Eastern Zhou Dynasty, with a history of over 2,000 years. The ball-shaped bell is a hollow bronze object with a hole in the center. Eight triangular holes are evenly spaced radially outward. It is divided into 3 parts, a ball, a neck, and a hollow pedestal (narrow at the top and wide at the bottom).
实际上，它的真实名字叫铜銮铃，是东周时期的一件车马器，距今已有2000余年的历史。铃球为圆形铃腔，正面中间一孔，向外呈辐射状等距分布八个三角形镂孔。整体分为铃球、铃颈和銎座三部分。底座上窄下宽，呈台状，也是中空结构。
With this object, the carriage makes a beautiful and pleasant sound when it runs.
銮铃是马车的装饰器，马车跑起来时能发出动人悦耳的声音。
From the Stone Age to the Iron Age, our history has proved that: As tools advanced, so did civilizations.
