A photo taken on May 19, 2016 shows flowers cascading down a building on a campus in South China's Guangxi Zhuang autonomous region. In summer, flowers can be seen everywhere in south China. But a flower "waterfall" on a campus in Guangxi still catches much attention, as this "flower waterfall" cascades down a five-floor building, measuring 15 meters high. Looking from afar, the cascading flowers look like a violet cape draping over the building's shoulder.[Photo/IC]
