Despite the uniformity of Chinese surnames, Chinese given names can be fairly original because Chinese characters can be combined extensively. Unlike European languages with their Biblical and Greco-Roman heritage, the Chinese language does not have a particular set of words reserved for given names: any combination of Chinese characters can theoretically be used as a given name. Nonetheless, a number of popular characters commonly recur, including "Strong" (, "Wěi"), "Learned" (, "Wén"), "Peaceful" (, "Ān"), and "Beautiful" (, "Měi"). Despite China's increasing urbanization, a great many namessuch as "Pine" (, "Sōng") and "Plum" (, "Méi")also still reference nature.
