Why is the national flag of South Korea a combination of Yin-Yang fish and four hexagrams in eight diagrams?

Since 1883, South Korea has been using Taiji flag. Used after the establishment of the Republic of Korea. 1949, the Ministry of Education, Culture, Sports, and Sports officially confirmed the current style of the Korean national flag: the center of the flag is Tai Chi pattern with eight diagrams around it. According to the official explanation of South Korea, the red in the Taiji diagram represents Yang, the blue represents Yin, and drinking Yin and Yang represents the balance and harmony of the universe. Fire and water, day and night, darkness and light, construction and destruction, male and female, active and passive, hot and cold, positive and negative, as two major forces in the universe, achieve harmony and balance through mutual opposition.

With the ether as the center, the four hexagrams symbolize the harmony of Yin and Yang, the dry hexagrams represent the sky, the Kun hexagrams represent the earth, the Kan hexagrams represent the moon and water, and the departure hexagrams represent the sun and fire. Each six-pointed star also symbolizes justice, richness, vitality and wisdom. According to South Korea's explanation, the background color of the national flag is white, which symbolizes the purity and love for peace of the Korean people. The whole national flag represents the ideal of the Korean people to develop harmoniously with the universe forever.

The thought of Tai Chi and Eight Diagrams of the Korean flag comes from China's Zhouyi. The principles of harmony, symmetry, balance, circulation and stability represent the profound thinking of the Chinese nation on the universe and life. The Korean Peninsula has been influenced by China culture for a long time, and the Korean flag is the embodiment of this influence.
