I walk pass the other side of it everyday as the shortest path to get to my work place. It looks like it's holding a massive dong. The back of it should really be against a building since on the other side of it, it's leading to a massive shopping street, therefore a lot of people who try to access the subway station 40 meters from it when coming out of the shopping street will just see an arm holding a massive dong. It's also one of the most busy subway station there as it connects to multiple lines there.
