Who are the famous innovators in Korea?

Doseon Guksa-Doseon is a Buddhist monk who was born at the end of the unified Silla Dynasty. He was regarded as a child prodigy since he was a child. He was highly valued by Buddhism before he was 20 years old, and finally went to China for further study in the Tang Dynasty, where he became interested in Taoism. During this period, he became interested in Feng Shui, or the types of Feng Shui in China. Although some influences of geomantic omen have existed in Korea for a long time, its practice has not been widely popularized, partly because it is not suitable for the geographical location of Korea.

After returning to South Korea, he carefully studied the geography of the motherland and adjusted Feng Shui to the present "Fengsu-Jiri", which seems to contain elements of Buddhism and Korean Shamanism. During the rise of the newly established Koryo dynasty, he was assigned to build several monasteries, and his new theory had an immediate impact. Centuries later, when kings and nobles decided on the location of their palaces and residences, they still took Paramount as a consideration.

Dossen's portrait Cui Wushan, who lived in the Koryo dynasty, is widely regarded as the person who brought gunpowder technology to South Korea. Although it has existed in China for centuries, strict control of gunpowder prevented its formula from spreading to other parts of Asia. As a military commander, Cui Longhai was deeply impressed by China fireworks and deeply understood the value of gunpowder technology. To this end, he devoted most of his life to exploring the formula of gunpowder to enhance the national strength.

By studying the observation records of this technology, the reverse engineering samples smuggled from China and the long trial and error process, Cui Renhai finally found the formula. Thanks to his efforts, South Korea was able to produce gunpowder at home, eliminating China's monopoly on this technology. Since then, he has also invented some of the earliest gunpowder-based weapons in North Korea, the most famous of which is the rocket-propelled arrow. In the following centuries, Koreans continued to improve their gunpowder weapons, some of which were invented by Cui Longhai himself.

South Korea's "hwacha", a device that can launch 100 Cui Shi's "singijeon" at most. I'm not kidding. This is really a rocket launcher made in15th century.

South Korean politician and intellectual Zheng Daoquan has the same responsibility for the establishment of the Korean dynasty as King Oto himself. Because of his close relationship with Yi Chengkui (later King Otsuka), he was appointed as the first prime minister of the Korean dynasty, mainly responsible for organizing the entire political structure of North Korea. Deeply influenced by Neo-Confucianism in China, he highly criticized the negative influence of Buddhism on the government and transformed Korea from a Buddhist feudal society into a secular and centralized bureaucracy. He also reorganized the North Korean caste system based on occupation, with bureaucrats at the upper level, farmers, laborers and craftsmen at the lower level, and monks and artists at the lower level. Because this essentially eliminates the hereditary factors in the caste system, people can improve their social status (technically speaking).

King Sejong, many people may think this is a bit blasphemous. Not to mention him, King Sejong is not only regarded as one of the most important innovators in Korean history, but also one of the most important figures. Accompanied by many innovations, his rule was largely defined as improving the lives of ordinary people through various means. For example, he ordered the revision of the calendar, and changed the capital of North Korea to the main meridian instead of the capital of China, thus greatly improving the accuracy of predicting the stars. However, the most important innovation created by King Sejong himself is the creation of the Korean letter: Korean. Before that, South Korea relied entirely on China's writing system.
