In the "Clear Sky with a White Sun" flag of Lu Hao-tung, the twelve rays of the white Sun symbolize 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 colors 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 tricolor of the Republic of China is the same as the French tricolor. The colors also represent the same concepts: liberty, equality, and fraternity. However, blue, for example, in the Chinese tricolor represent equality and red represent liberty.
