Later generations mistakenly thought it was a fish pond in Tang Yin. According to relevant public information, "Yun Yu Tang" is another name of Tang Yin, a painter in the Ming Dynasty. He often signs "Fish Hall" on his paintings. Later generations mistook Lang Shining's paintings for Tang Yin's works, so they wrote "Fish House" as "Fish House". The fish theater post is a 10 copy of "Chunhua Pavilion Post" written by Liu Cizhuang in the seventh year of Song Dynasty (1092). Because it is engraved on the wall of Linjiang Fish Theatre, it is called "Linjiang Fish Theatre Post" or "Linjiang Post".
