When shopping at Qipu Road (七浦路) Shanghai the other day, I found this escalator in one of the shopping malls. It is absolutely the weirdest escalator I have ever seen. The practical purpose of this flap-like thing is to prevent the cold air inside the mall from flowing out ( or is it the other way? haha ) but this is absolutely the lamest thing I have ever seen in my life. I had to use kick and use my legs to pry open the flap-like thing because who knows how dirty it might be. uggh.
p.s.: Qipu Road is great news for girls as it is a shopping heaven!
