The Taiwan flag, officially the flag of the Republic of China, is formally known as “Blue Sky, White Sun, and a Wholly Red Earth”. This national flag of Taiwan displays a red field with a blue canton in the upper hoist-side corner that contains a white sun with twelve triangular rays. The design became standardized in 1928 and later appeared in the 1947 Constitution of the Republic of China as the official national flag.
In most references, Taiwan's flag meaning links directly to its three colors and symbols. The blue canton represents liberty, justice, and democracy. The white sun and its twelve rays symbolize equality and continuous progress. The red field stands for fraternity, sacrifice, and nationalism. Together, these elements shape Taiwan flag symbolism in encyclopedic and vexillological discussions.
