Huitong Temple (汇通祠)

Located at the island in the northwest of Shichahai, Huitong Temple was built during the reign of Emperor Yongle of the Ming Dynasty. It was once called Fahua Temple and then changed to Zhenshui Guanyin Temple. In the 26th year under the reign of Emperor Qianlong in the Qing Dynasty, the Emperor especially indited a poem for praising Huitong Temple.

In the backyard of the temple, there is a statue of Guo Shoujing, a famous scientist of the Yuan Dynasty in China. He not only invented more than a dozen kinds of astronomical instruments such as abridged armilla, scaphe, and the gaobiao (giant Chinese gnomon), but also calculated the famous Shoushi Calendar, according which 365.3425 days constitute one year. This achievement was made 300 years earlier than that of Europe.
