Introduction to the Nine-Bend Corridor: The Nine-Bend Corridor is located to the west of the Science and Education Museum. It was originally a five-curved bamboo structure built in 1954. In 1972, it was converted into a nine-curved corridor with a reinforced concrete structure. The corridor has a flat roof, a leaky window in the north corridor wall, and a corridor column in the south. The total length is more than 70 meters, and the construction area is 320 square meters.
