在皇宫里，根据不同的地点也会安置不同的铜大缸雕塑来作为装饰，作为紫禁城中最重要的中轴线，从太和殿、中和殿、保和殿到乾清宫这一条直线上，均匀的将18口鎏金的吉祥缸分布其中，错落有致。至于为什么要将鎏金的铜大缸雕塑摆放在这些位置，那是因为这些位于中轴线上的宫殿是皇宫中体量大的建筑，而鎏金的铜大缸雕塑也是所有门海中蓄水量大的，所以为了大限度的保证灭火用水的充足，自然要将这些大号的吉祥缸摆放在这条中轴线上。

In the palace, according to different locations, different copper cylinder sculptures will be placed as decoration, as the most important central axis of the Forbidden City, from the Taihe Hall, Zhonghe Hall, Baohe Hall to the Qianqing Palace in a straight line, evenly 18 golden auspicious cylinders are distributed among them, which are staggered. As for why the Bronze Cylinder sculptures of gold are placed in these places, it is because the palace on the central axis is a large building in the palace, and the Bronze Cylinder sculptures of gold are also a large amount of water storage in all the doors and seas, so in order to ensure sufficient water for fire extinguishing, naturally these large auspicious cylinders should be placed on this central axis.
