In the "Clear Sky with a White Sun" flag of Lu Hao-tung, the twelve rays of the white Sun symbolise the twelve months and the twelve traditional Chinese hours, each of which corresponds to two modern hours. Sun Yat-sen added the "Red Earth" to the flag to signify the blood of the revolutionaries who sacrificed themselves to overthrow the Qing Dynasty and create the ROC. Together, the three colours of flag correspond to the Three Principles of the People:
* Blue represents nationalism and liberty.
* White represents democracy and equality; and
* Red represents the people's livelihood and fraternity;
Of note, the tricolour of the Republic of China is the same as the French tricolour. The colours also represent the same concepts: liberty, equality and fraternity. However, blue, for example, in the Chinese tricolour represent equality and red represent liberty.
