Blue Sky with a White Sun
When the government of the Republic of China was established on January 1, 1912, The "Five-Colored" flag was adopted as the national flag, but Sun Yat-sen did not consider its design appropriate, reasoning that horizontal order implied a hierarchy or class like that which existed during dynastic times. Thus, when he established a rival government in Guangzhou in 1917, he brought over the "Blue Sky with a White Sun" flag for the party and the "Blue Sky, White Sun, and a Wholly Red Earth" () flag, which was then the naval ensign, for the nation. This officially became the national flag in 1928 while the "Blue Sky with a White Sun" flag was adopted as the naval jack.
