乾清门外两侧的10口铜大缸格外引人注目。铜大缸金光闪闪，在红色宫墙的映衬下，赤行富丽堂后皇，气热血甚壮。然而，这些铜大缸和大铁昔日皇宫却不是装饿用品，而是用来贮水的防火用具。缸内平时注潢汪水，随时可以灭火。

The 10 copper VATS on both sides of the Qianqing gate are particularly striking. The copper VAT is glittering with gold. Against the red palace wall, the empress of the red hall is very strong. However, these copper vats and iron imperial palaces used to be fire-proof appliances for storing water instead of food. Water is usually injected into the cylinder to extinguish the fire at any time.

到了冬季，为了防止结冰，专有内务府太监负责在缸外套上校风套保温并加盖，缸底还要烯起炭火，直到来年春暖时才撤火。故宫博物院成立以后，为防止缸内积水，在缸底均钻有漏水孔。

In winter, in order to prevent freezing, the eunuch of the exclusive interior office is responsible for the heat preservation and capping of the captain's air sleeve on the cylinder jacket, and the bottom of the cylinder needs to be filled with carbon fire until the next spring warm. After the establishment of the Palace Museum, in order to prevent water accumulation in the tank, water leakage holes were drilled at the bottom of the tank.
