故宫铜缸雕塑铸造厂除了制作过程耗费财物之外，照看它们也颇为费力，在夏季这些吉祥缸需要内务府内管领处的苏拉(杂役)每日照看，及时添水换水。内务府内管领处是负责宫中日常事务和管理杂役的地方，如此庞大的皇宫仅有内管领太监30人，而在这其中就有一位首领太监是专门负责照看吉祥缸的。照看这些故宫铜缸雕塑铸造厂麻烦的是到了北京干冷的冬季之后，由于皇帝担心火灾的发生，所以在清代内务府编辑的《钦定宫中现行则例》的“安设”一条中规定：“凡宫内各处铜缸、铁缸，每逢小雪节，该管首领太监安设缸盖缸套···等至开年惊蛰收回”，并且在每个大缸底部还用石头垒成一个小的灶台，点火熏灼，大缸每日给黑炭四斤，小缸三斤，昼夜不停以免上冻。而这一切的原因就是为了一个目的——防火!（铜大缸厂家）

In addition to the cost of the production process, the copper cylinder sculpture foundry of the Forbidden City takes a lot of effort to look after them. In the summer, these auspicious cylinders need to be looked after by Sula (the worker) in the office of the internal affairs office every day, adding water and changing water in time. The office of internal affairs is responsible for the daily affairs of the palace and the management of miscellaneous workers. There are only 30 eunuchs in such a huge palace. Among them, there is a chief eunuch who is specially responsible for looking after the auspicious urn. The trouble of looking after these copper cylinder sculpture foundries in the Forbidden City is that after the cold and dry winter in Beijing, because the emperor was worried about the fire, it was stipulated in the article "installation" of the current rules of the Imperial Palace edited by the Ministry of internal affairs in the Qing Dynasty: "every time there are copper and iron cylinders in the palace, the chief eunuch of the imperial palace will install cylinder heads and cylinder liners at every Snow Festival... Etc. until the beginning of the year, he will recover them by waking up." And at the bottom of each big tank, a small stove is made of stone, which is ignited and burned. The big tank gives four Jin of black carbon and three jin of small tank every day, so as to avoid freezing day and night. And the reason for all this is for one purpose - fire prevention!
