On the New Year’s Day holidays 2015, at the platform at Xizhimen station, you can see sheep of all postures dancing on the wall. This is another graffiti art show at BJL4 lines following the 3D picture “Horse Foretell Success” at Lingjing Hutong station last year - the Year of Horse. The aim is to share the beauty of zodiac culture and provide a rich, comfortable and vogue visual environment for the passengers. It is also an vehicle to conduct in-depth communication with passengers and provide them better riding experiences.
