Lee (Korean Name)
Lee, I, or Yi () is the second-most-common surname in Korea, behind Kim (김). Historically, 李 was officially written as Ni () in Korea. The spelling officially changed to I () in 1933 when the initial sound rule () was established. In North Korea, it is romanized as Ri () because there is no distinction between the alveolar liquids /l/ and /r/ in modern Korean. As of the South Korean census of 2015, there were 7,306,828 people by this name in South Korea or 14.7% of the population. Latin-alphabet spelling Though the official Revised Romanization spelling of this surname is I, South Korea's National Institute of the Korean Language noted in 2001 that one-letter surnames were quite rare in English and other foreign languages and could cause difficulties when traveling abroad. However, the NIKL still hoped to promote systemic transcriptions for use in passports, and thus recommended that people who bore this surname should spell it Yi in the Roman alphabet. However, t ...

Confucianism
Confucianism, also known as Ruism or Ru classicism, is a system of thought and behavior originating in ancient China. Variously described as tradition, a philosophy, a religion, a humanistic or rationalistic religion, a way of governing, or a way of life, Confucianism developed from what was later called the Hundred Schools of Thought from the teachings of the Chinese philosopher Confucius (551–479 BCE). Confucius considered himself a transmitter of cultural values inherited from the Xia (c. 2070–1600 BCE), Shang (c. 1600–1046 BCE) and Western Zhou dynasties (c. 1046–771 BCE). Confucianism was suppressed during the Legalist and autocratic Qin dynasty (221–206 BCE), but survived. During the Han dynasty (206 BCE–220 CE), Confucian approaches edged out the "proto-Taoist" Huang–Lao as the official ideology, while the emperors mixed both with the realist techniques of Legalism. A Confucian revival began during the Tang dynasty (618–907 CE). In the late Tang, Co ...

National Security
National security, or national defence, is the security and defence of a sovereign state, including its citizens, economy, and institutions, which is regarded as a duty of government. Originally conceived as protection against military attack, national security is widely understood to include also non-military dimensions, including the security from terrorism, minimization of crime, economic security, energy security, environmental security, food security, and cyber-security. Similarly, national security risks include, in addition to the actions of other nation states, action by violent non-state actors, by narcotic cartels, and by multinational corporations, and also the effects of natural disasters. Governments rely on a range of measures, including political, economic, and military power, as well as diplomacy, to safeguard the security of a nation state. They may also act to build the conditions of security regionally and internationally by reducing transnational ca ...

Neo-Confucianism
Neo-Confucianism (, often shortened to ''lǐxué'' 理學, literally "School of Principle") is a moral, ethical, and metaphysical Chinese philosophy influenced by Confucianism, and originated with Han Yu (768–824) and Li Ao (772–841) in the Tang Dynasty, and became prominent during the Song and Ming dynasties under the formulations of Zhu Xi (1130–1200). After the Mongol conquest of China in the thirteenth century, Chinese scholars and officials restored and preserved neo-Confucianism as a way to safeguard the cultural heritage of China. Neo-Confucianism could have been an attempt to create a more rationalist and secular form of Confucianism by rejecting superstitious and mystical elements of Taoism and Buddhism that had influenced Confucianism during and after the Han dynasty. Although the neo-Confucianists were critical of Taoism and Buddhism, the two did have an influence on the philosophy, and the neo-Confucianists borrowed terms and concepts. However, unlike the ...

Myeongjong Of Joseon
Myeongjong of Joseon (3 July 1534 – 3 August 1567, r. 1545–1567) was the 13th king of the Joseon Dynasty of Korea. He was the second son of Jungjong, and his mother was Queen Munjeong, who was Jungjong's third queen. He became king in 1545 at the age of 12 following the death of his half-brother, Injong. Since he was too young to rule the kingdom, Queen Munjeong governed the nation in his name. Biography Political factions There were two political factions at the time Myeongjong came to power; Greater Yun, headed by Yun Im, Injong's maternal uncle, and Lesser Yun, headed by Myeongjong's maternal uncles, Yun Won-hyeong and Yun Wonro. (Yun Im and Yun Brothers were close relatives by that period's standards - Yun Im was a third cousin once removed of Yun Brothers.) Greater Yun took power in 1544, when Injong succeeded Jungjong; but they failed to wipe out their opposition, since Queen Munjeong protected the Lesser Yun faction and other opposition officials.

Ming Dynasty
The Ming dynasty (), officially the Great Ming, was an imperial dynasty of China, ruling from 1368 to 1644 following the collapse of the Mongol-led Yuan dynasty. The Ming dynasty was the last orthodox dynasty of China ruled by the Han people, the majority ethnic group in China. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the short-lived Shun dynasty), numerous rump regimes ruled by remnants of the Ming imperial family—collectively called the Southern Ming—survived until 1662. The Ming dynasty's founder, the Hongwu Emperor (r. 1368–1398), attempted to create a society of self-sufficient rural communities ordered in a rigid, immobile system that would guarantee and support a permanent class of soldiers for his dynasty: the empire's standing army exceeded one million troops and the navy's dockyards in Nanjing were the largest in the world. He also took great care breaking the power of the court eunuchs and ...

Taoism
Taoism (, ) or Daoism () refers to either a school of philosophical thought (道家; ''daojia'') or to a religion (道教; ''daojiao''), both of which share ideas and concepts of Chinese origin and emphasize living in harmony with the '' Tao'' (, 'Thoroughfare'); the ''Tao'' is generally defined as the source of everything and the ultimate principle underlying reality. The ''Tao Te Ching'', a book containing teachings attributed to Laozi (), together with the later writings of Zhuangzi, are both widely considered the keystone works of Taoism. Taoism teaches about the various disciplines for achieving perfection through self-cultivation. This can be done through the use of Taoist techniques and by becoming one with the unplanned rhythms of the all, called "the way" or "Tao". Taoist ethics vary depending on the particular school, but in general tend to emphasize '' wu wei'' (action without intention), naturalness, simplicity, spontaneity and the Three Treasures: , compassio ...
