Wu Gong refers to Wu Gong, which is the main street of Pingjiang Historic District on Pingjiang Road in Suzhou today. Located on the north side of the east bank of Ganjiang East Road Court Bridge, it starts from Ganjiang East Road in the south and connects Baita East Road and Dongbei Street in the north, so it was called "Li Shiquan" in ancient times. Its history can be traced back to the courtyard of the King of Wu in the Spring and Autumn Period in the 6th century BC. There are still ruins of the King of Wu in Suzhou, such as the amphibious panmen planned and built by the famous minister Wu Zixu in the Spring and Autumn Period. Now it is a rare well-preserved Panmen Tower in China.
