It is listed among the 72 famous springs (Chinese: 七十二名泉; pinyin: Qīshí'èr Míng Quán) of Jinan (as number 19.).
The name "Zhuoying Spring" comes from a poem from Mencius, "Li Lou Shang" (Chinese: 离娄上; pinyin: Lí Lóu Shàng), that contains the phrase "wash out the tassel" (Chinese: 濯缨; pinyin: zhuó yīng).
[1] When the army of the Jin dynasty invaded Jinan moving southward into the territory of the Southern Song dynasty, the local garrison commander, Guan Sheng (Chinese: 关胜; pinyin: Guān Shèng), refused to surrender.
A bloody battle ensued and the soldiers washed the textile decorations of their lancets in the Palace Pool.
[1] Today, the pool lies in a historical residential neighborhood with private residences on the water edge.
