On the Bank of the East Bank of the summer palace is a gilded bronze bull the size of a real bull. It was cast in the 20th year of Qianlong's reign in the Qing Dynasty. It has a fine and lifelike image. On the back of the bull, there is a four character inscription specially engraved by Emperor Qianlong in seal script. The inscription expounds the significance of building a bronze bull, hoping that it can keep the flood in check and bring benefits to the people.
The ancient sculptures in China are mostly freehand, but this bronze bull only adopted the realistic technique. It has lifelike shape, vivid expression, bright eyes, and rich and delicate artistic expression techniques, which represent the superb casting level at that time.
