At the line's west end, mosaics on eight arch walls at the Yangzhuang station feature the Eight Scenic Spots of Beijing. At the Xihuangcun station, riders can be enthralled by a mosaic featuring white deer frolicking under the golden ginkgo trees, a beloved symbol of the city's autumn.

Like Beijing, another ancient Chinese capital Xi'an has also turned its metro stations into underground mosaic galleries to showcase its splendid, inclusive culture during the Tang Dynasty (618-907). Other Chinese cities including Nanjing, Chengdu, and Qingdao have also followed suit by adorning their metro systems with mosaic murals.
