The Korean flag was first designed by Ma Jianzhong, an envoy of the Qing Dynasty in charge of Korea, when there was only one country on the peninsula, called North Korea; at that time, South Korea needed to trade with Britain, and after signing an agreement to raise the flag, there was no flag; as a qing dynasty vassal state, he applied for the use of the dragon flag; the first time Ma Jianzhong considered the vassal state, and was allowed to use the dragon flag after reporting to the imperial court, but it could only be four claws, and the color was required, and the Koreans felt troublesome. Later, Ma Jianzhong designed the Bagua diagram, at that time, there was Bagua next to the Taiji Yin yang fish, and the Bagua represented the Eight Ways of Korea (Dao is similar to our province in Korea), but after they took it, the British changed the color and removed the four gua. Eventually it became the current Taiji diagram (without eyeballs) and only four gua (heaven and earth, water and fire); later this figure was transmitted back to China, because the yin and yang fish lacked dots to reconcile yin and yang, and also lacked the harmony of the four gua; it was considered by Taoism to have no eyes and no beads, red and blue, and water and fire were intolerable. As a result, as we see now, the two sides of the Korean Peninsula are opposite and cannot be blended.
