铜缸也叫吉祥缸。清代宫中各处陈设吉祥缸。但它们的质地、大小、多少都要随具体的环境而定。比如鎏金铜缸等级最高，（铜大缸）因此要设列在皇帝上朝议政的太和殿、保和殿两侧以及用于“御门听政”的乾清门外红墙前边。而在后宫及东西长街，就只能陈设较小的铜缸或铁缸了。
The bronze jar is also called auspicious jar. In the Qing Dynasty, auspicious VATS were set up everywhere in the palace. But their texture, size and number depend on the specific environment. For example, the gilded bronze jar has the highest level, so it should be set on both sides of the Taihe hall and Baohe hall where the emperor discussed politics, and in front of the red wall outside the Qianqing gate, which was used to "listen to the imperial gate". In the Hougong and the East-West long street, only small copper or iron VATS can be displayed.

名为“吉祥缸”的盛水容器直径和高度都超过1米，青铜材质的吉祥缸重量至少6000斤，容量也可以达到数千升。夏季，由于气温高，水分蒸发速度快，每天都会有数十名太监专门负责往“吉祥缸”内加水、换水，保证水容量充足没有异味；冬季，为了防止气温低结冰，从每年的农历10月起至次年3月止，除了保证水量充足外，太监和杂役们还会给吉祥缸加盖、套上棉套，同时在水缸下放上引燃的木炭，保证缸里的水不结冰，时刻处于可用状态。
The diameter and height of the water container named "auspicious jar" is more than 1 meter. The bronze auspicious jar weighs at least 6000 Jin and its capacity can reach thousands of liters. In summer, due to the high temperature and rapid evaporation of water, dozens of eunuchs are specially responsible for adding water and changing water into the "auspicious jar" every day to ensure sufficient water capacity without peculiar smell; in winter, in order to prevent low temperature and freezing, from October of the lunar calendar to march of the next year, in addition to ensuring sufficient water, eunuchs and laborers will cover and cover the auspicious jar, and at the same time The charcoal ignited on the lower part of the water tank ensures that the water in the cylinder does not freeze and is always available.
