in 1924 and was set as the national emblem by the Law of national flag and national emblem of the Republic of China in 1928. On the national emblem rays of sun have some distance to the edge, symbolizing the broadness of the sky, while on Kuomintang emblem the rays reach the edge, symbolizing the spirit of revolution is as powerful as the sun. 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. Nationalist period Since 1928, under the KMT's political tutelage, the Blue Sky with a White Sun Flag shared the same prominence as the ROC flag. A common wall display consisted of the KMT flag perched on the left and the ROC flag perched on the right, each tilted at an angle with a portrait of National Father Sun Yat-sen displayed in the center. After the promulgation of the Constitution of the Republic of China, the party flag was removed from such a display and the national flag was moved to the center. To promote a sense of national identity, the design of the national emblem was freely available to use and was featured prominently in corporate logos, art during the era. Taiwanese period Since the ROC government moved to Taiwan and especially in the years since the end of martial law the KMT flag has lost some of its prominence. However, it is still frequently seen on KMT party buildings, in political rallies and other meetings of KMT and the pan-blue coalition. The flag and the symbol made news during the ROC legislative elections of 2004, when President Chen Shui-bian suggested that the Kuomintang's flag and party emblem violated the ROC's National Emblem Law for being too similar to the national emblem of the Republic of China. Chen stated that the law forbids the ROC's emblem and flag from being used by non-governmental organizations and warned that the KMT would have three months to change its flag and emblem
