Liu Xingxing plays on the "castle", a newly-built wall, in Qiqili Village of Yonghe County, north China's Shanxi Province, Feb. 11, 2018. Liu Xingxing is a little girl growing up in city. She can only return to her hometown, Qiqili Village, during winter and summer holidays. In this 9-year-old girl's eyes, the development in the past few years magically turned the once-poor-and-remote village into a "castle" with galleries and tourism attractions. (Xinhua/Cao Yang)
