The original intention of setting up a large number of copper tanks in the palace is to prevent fire, but the actual value is not limited to fire, it is also an indispensable display in the palace hall and courtyard. In the Qing Dynasty, the quality, size and quantity of auspicious jars in the palace were determined by the specific environment. The gilded bronze tanks are of different grades. Therefore, they should be set on both sides of the hall of Supreme Harmony and the hall of Baohe, and in front of the red wall outside the palace of Qianqing, which is used for "the imperial gate to listen to the government". In the rear palace and the east-west street, they can only display smaller copper tanks or iron tanks.
