Flag of Taiwan

Taiwan's flag features a red field with a navy blue canton in the upper left corner. Centered within the canton is a white sun with twelve triangular rays emanating outwards. The flag's aspect ratio is 2:3.

The blue field represents liberty and nationalism, while the white sun symbolizes equality and fraternity, principles espoused by Sun Yat-sen. The twelve rays of the sun represent the twelve months and the twelve traditional Chinese hours, symbolizing progress. The red field is said to represent sacrifice for the nation, as well as Han Chinese ethnicity.

The flag was first designed by Sun Yat-sen and later modified by He Yingqin. Initially, it served as the Kuomintang (KMT) party flag. It officially became the flag of the Republic of China (ROC) in 1928. Following the Chinese Civil War and the ROC's relocation to Taiwan in 1949, the flag continued to be used as the national flag.
