Since the event website is in Chinese, I shall introduce the content to you in English! However, if you are comfortable with reading Chinese, simply go to this website and vote! (http://sh.sina.com.cn/shmetrodsn/)
You need a valid Chinese ID number and a phone number to vote.
Now let's take a look at all the designs! (Click on any of them to enlarge!)
Design 1: A Trip to Disney
This design uses elements of Disney Characters to decorate the station.
Its biggest highlight is that they are going to decorate the tunnel with film stills (each one slightly different from the previous) from Disney films so that when the train passes them, they will form an animation. (cool!)
