Introduction to Hongqiao: Built in the ninth year of Kangxi reign of the Qing Dynasty (1670), it was originally named Wohong Bridge. It was rebuilt in the third year of the Republic of China and renamed Hongqiao. The bridge has two piers and three holes. It is a stone arch bridge built with red strips of sand and stone on the wooden floor. There were 12 stilted wooden houses on each side of the original bridge deck, with restaurants and department stores, and a 2-meter-wide pedestrian corridor in the middle. There is a roof above the corridor, which provides shelter from wind and rain, so it is also called the Wind and Rain Tower.
