在故宫中，大殿前、庭院中都有摆放铜大缸，这些故宫铜大缸是雕塑工艺中的一种铸铜雕塑，腹宽口收，容量极大，而且装饰精美，两耳处加饰有兽面铜环，?据说，这些铜大缸雕塑最初是用来防火的，因故宫中的主要建筑材质以木质为主，很易引起火灾，而在通常在门口的铜大缸中注满水，以备不时之需。但是这些铜大缸实际存在的意义不仅局限于消防，同时还是宫内大殿等的陈列品，这些吉祥铜大缸雕塑在材质上多选用优质青铜而铸，以鎏金铜大缸等级最高，也最显豪华高贵，而一些后宫及长街，则摆设一些小铜缸或铁缸。
In the Palace Museum, there are large copper VATS in front of the palace hall and in the courtyard. These copper vats are cast copper sculptures in the sculpture process. They have a wide belly, a large capacity and exquisite decoration. The two ears are decorated with bronze rings with animal faces. It is said that these copper VATS were originally used for fire prevention. Because the main building material of the Palace Museum is wood, it is easy to cause fire Fill the copper vat at the door with water in case of emergency. However, the practical significance of these large bronze VATS is not only limited to fire fighting, but also the exhibits of the palace hall. These auspicious Bronze Cylinder sculptures are mostly made of high-quality bronze. The gilded bronze VATS have the highest grade and show the most luxury and nobility. Some palaces and long streets are decorated with small copper or iron vats.

中国人爱风水，不管什么东西都要和风水扯上关系，所谓“藏风聚气，得水为上”，所以在很多中国人家中，当自然条件无法满足依山傍水的需求时，就会摆放一些水缸、鱼缸之类的充数。但要是说到摆放水缸多的地方，那就非“天下家”的紫禁城莫属了，在讲究等级庄严的皇宫大内，从前朝到后宫布置这么多的水缸，宫里难道也是为了调理风水才这么做的吗?
Chinese people love Feng Shui. No matter what they do, they have to have something to do with it. The so-called "storing wind and gathering Qi, getting water is the most important thing". Therefore, in many Chinese families, when natural conditions can not meet the needs of mountains and rivers, they will place some water tanks, fish tanks and other sufficient quantities. But when it comes to the places where there are lots of water tanks, it's the Forbidden City of the "family of the world". In the Imperial Palace, which pays attention to the solemnity of hierarchy, there are so many water tanks arranged from the former dynasty to the back palace. Is it also for the purpose of regulating geomantic omen in the palace?
