The national emblem of the Republic of China from 1913 to 1928 is called Twelve Symbols national emblem, based on the traditional symbols on clothes of ancient Chinese emperors. It was designed by Lu Xun, Qian Daosun and Xu Shoushang on August 28, 1912 and was set as national emblem in February 1913. It remained as the national emblem during the Empire of China from 1915 to 1916. After the Northern Expedition it was replaced by the Blue Sky with a White Sun national emblem in 1928.
