Wukang Building is an apartment building located at the junction of Huaihai Middle Road and Wukang Road. Because of its unique shape and long history, it is also a tourist attraction now. It can walk about five minutes from the subway station of Jiaotong University to a corner above a crossroad. When it comes to it, you can see many people taking pictures. The shape of the building has a little triangle, which actually looks like one of the versions of the New York Iron Building. It was built in 1920 or so. European designers and the whole building were mainly made of stone, so it is more durable. Up to now, many ordinary residents still live upstairs. The building can be visited, but it's normal to go up. Just look at the internal architecture.
