Yi'an Center is a landmark building here. The easiest thing to see is this high building, 300 stories high, very magnificent.
More than 300 meters of buildings are now one of the highest in Chicago, with no extra wires and lightning rods to make the net height more technical. The huge dark glass curtain wall with white stone wraps the whole square building. It is said that it was created in 1992 when it was renovated. The 80-storey office building is also the office choice of many famous international enterprises.
