Juxing Court, located in the west of Lingxingmen of Nanjing Confucius Temple, corresponds to Kuiguang Pavilion in the west of Lingxingmen, symbolizing the prosperity of writing style. It is an ancient pavilion with eight sides and two floors. It was founded in the 14th year of Wanli in Ming Dynasty (AD 1586). It is also a famous monument with a long history of Confucius Temple. It was destroyed for hundreds of years, and in the eighth year of Tongzhi in Qing Dynasty (AD 1869), it was renovated for the last time with the financing of Zhu Fufeng, a rural sage in Jiangning. It's hard to read, but it was preserved until the 1960s. During the Cultural Revolution, it was torn down as "tattered capitalism". The present Juxing Court was rebuilt by 1984.
