Question: Information:  - Korea is a historical state in East Asia, since 1945 divided into two distinct sovereign states: North Korea (officially the "Democratic People's Republic of Korea") and South Korea (officially the "Republic of Korea"). Located on the Korean Peninsula, Korea is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the East Sea.  - Cao Huan (246-303), courtesy name Jingming, was the fifth and last emperor of the state of Cao Wei during the Three Kingdoms period. In 265, he abdicated the throne in favour of Sima Yan (later Emperor Wu of the Jin dynasty), and brought an end to the Wei regime. After his abdication, Cao Huan was granted the title "Prince of Chenliu" and held it until his death, after which he was posthumously honoured as "Emperor Yuan (of Cao Wei)".  - Chen Qun ( died 236 ) , courtesy name Changwen , was a minister of the state of Cao Wei during the Three Kingdoms period . Chen Qun initiated the Nine - rank system for civil service nomination in Wei . Following the death of the first Wei ruler Cao Pi , Chen Qun became the Guardian of Wei 's military forces . Chen Qun , Sima Yi and Cao Zhen nominated Cao Pi 's son , Cao Rui , to become the new emperor .  - Liu Bei (161  10 June 223), courtesy name Xuande, was a warlord in the late Eastern Han dynasty who founded the state of Shu Han in the Three Kingdoms period and became its first ruler. Despite early failings compared to his rivals and lacking both the material resources and social status they commanded, he gathered support along disheartened Han loyalists who objected to Cao Cao's reign over the emperor and relied heavily on this support. Liu Bei overcame his many defeats to carve out his own realm, which at its peak spanned present-day Sichuan, Chongqing, Guizhou, Hunan, parts of Hubei, and parts of Gansu.  - A civil servant or public servant is a person in the public sector employed for a government department or agency. The extent of civil servants of a state as part of the "civil service" varies from country to country. In the United Kingdom, for instance, only Crown (national government) employees are referred to as civil servants whereas county or city employees are not.  - Cao Wei (220265) was one of the three major states that competed for supremacy over China in the Three Kingdoms period (220280). With its capital at Luoyang, the state was established by Cao Pi in 220, based upon the foundations laid by his father, Cao Cao, towards the end of the Eastern Han dynasty. The name "Wei" first became associated with Cao Cao when he was named the Duke of Wei by the Eastern Han government in 213, and became the name of the state when Cao Pi proclaimed himself emperor in 220. Historians often add the prefix "Cao" to distinguish it from other Chinese states known as "Wei", such as Wei of the Warring States period and Northern Wei of the Southern and Northern Dynasties. The authority of the ruling Cao family gradually weakened after the death of the second Wei emperor, Cao Rui, and eventually fell into the hands of Sima Yi, a Wei regent, and his family, in 249. Cao Rui's successors remained as puppet rulers under the control of the Simas until Sima Yi's grandson, Sima Yan, forced the last Wei ruler, Cao Huan, to abdicate the throne and established the Jin dynasty.  - Sun Quan (182252), courtesy name Zhongmou, formally known as Emperor Da of Wu (lit. "Great Emperor of Wu"), was the founder of the state of Eastern Wu during the Three Kingdoms period. He inherited control of the warlord state founded by his elder brother Sun Ce in 200. He declared formal independence and ruled from 222 to 229 as "King of Wu" and from 229 to 252 as the "Emperor of Wu". Unlike his rivals Cao Cao and Liu Bei, Quan governed his empire mostly separate of politics and ideology, he is sometimes portrayed as neutral considering he accommodated the wills of both his rivals but only when it benefited his state of Wu and never fully attempted to conquer his rivals, although most of historians would cite his lack of logistical resources to do so.  - Cao Rui (204 or 206  22 January 239), courtesy name Yuanzhong, was the second emperor of the state of Cao Wei during the Three Kingdoms period. His parentage is in dispute: his mother, Lady Zhen, was Yuan Xi's wife, but she later remarried Cao Pi, the first ruler of Wei. Based on conflicting accounts of his age, Pei Songzhi calculated that, in order to be Cao Pi's son, Cao Rui could not have been 36 (by East Asian age reckoning) when he died as recorded, so the recorded age was in error; Lu Bi and Mou Guangsheng argued instead that Cao Rui was Yuan Xi's son.  - A courtesy name ("zi"), also known as a style name, is a name bestowed upon one at adulthood in addition to one's given name. This practice is a tradition in East Asian cultures, including China, Japan, Korea, and Vietnam.  - The Three Kingdoms (AD 220280) was the tripartite division of China between the states of Wei, Shu, and Wu, following the Han dynasty and preceding the Jin dynasty. The term "Three Kingdoms" itself is something of a mistranslation, since each state was eventually headed not by a king, but by an emperor who claimed legitimate succession from the Han dynasty. Nevertheless, the term "Three Kingdoms" has become standard among sinologists. To further distinguish the three states from other historical Chinese states of similar names, historians have added a relevant character: Wei is also known as Cao Wei, Shu is also known as Shu Han, and Wu is also known as Dong (or Eastern) Wu.  - Guo Nüwang (184235), formally known as Empress Wende, was an empress of the state of Cao Wei during the Three Kingdoms period. She was married to Cao Pi, the first ruler of Wei.  - China, officially the People's Republic of China (PRC), is a unitary sovereign state in East Asia. With a population of over 1.381 billion, it is the world's most populous country. The state is governed by the Communist Party of China, and its capital is Beijing. It exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau), and claims sovereignty over Taiwan. The country's major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a great power and a major regional power within Asia, and has been characterized as a potential superpower.  - Japan ("Nippon" or "Nihon" ; formally "" or "Nihon-koku", means "State of Japan") is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, It is lying off the eastern coast of the Asia Mainland (east of China, Korea, Russia) and stretching from the Sea of Okhotsk in the north to the East China Sea and near Taiwan in the southwest.   - Temple names are commonly used when naming most Chinese, Korean (Goryeo and Joseon periods), and Vietnamese (such dynasties as Trn, Lý, and Lê) royalty. They should not be confused with era names. Compared to posthumous names, the use of temple names is more exclusive. Both titles were given after death to an emperor or king, but unlike the often elaborate posthumous name, a temple name almost always consists of only two characters:  - Cao Pi (187  29 June 226), courtesy name Zihuan, was the first emperor of the state of Cao Wei in the Three Kingdoms period. He was born in Qiao (; present-day Bozhou, Anhui) as the second son of Cao Cao, a warlord who lived in the late Eastern Han Dynasty. However, he was the eldest son among all the children born to Cao Cao by his concubine (later wife) Lady Bian. Of all his brothers, Cao Pi was the shrewdest. Instead of focusing on academic studies or administering military affairs, he was always in the presence of court officials in order to gain their support. He was mostly in charge of defence at the start of his career. After the defeat of Cao Cao's rival Yuan Shao at the Battle of Guandu, he took the widow of Yuan Shao's son Yuan Xi, Lady Zhen, as a concubine, but in 221 Lady Zhen died and Guo Nüwang became empress.  - The Han dynasty was the second imperial dynasty of China (206 BC220 AD), preceded by the Qin dynasty (221206 BC) and succeeded by the Three Kingdoms period (220280 AD). Spanning over four centuries, the Han period is considered a golden age in Chinese history. To this day, China's majority ethnic group refers to itself as the "Han people" and the Chinese script is referred to as "Han characters". It was founded by the rebel leader Liu Bang, known posthumously as Emperor Gaozu of Han, and briefly interrupted by the Xin dynasty (923 AD) of the former regent Wang Mang. This interregnum separates the Han dynasty into two periods: the Western Han or Former Han (206 BC  9 AD) and the Eastern Han or Later Han (25220 AD).  - Sima Yi (179  7 September 251), courtesy name Zhongda, was a general and politician of the state of Cao Wei in the Three Kingdoms period. He is perhaps best known for defending Wei from Zhuge Liang's Northern Expeditions. His success and subsequent rise in prominence paved the way for his grandson Sima Yan's founding of the Jin dynasty, which would eventually bring an end to the Three Kingdoms era. In 265 after the Jin dynasty was established, Sima Yi was posthumously honoured as Emperor Xuan of Jin with the temple name of Gaozu.  - The Warring States period was an era in ancient Chinese history following the Spring and Autumn period and concluding with the Qin wars of conquest that saw the annexation of all other contender states, which ultimately led to the Qin state's victory in 221 BC as the first unified Chinese empire known as the Qin dynasty. Although different scholars point toward different dates ranging from 481 BC to 403 BC as the true beginning of the Warring States, Sima Qian's choice of 475 BC is generally the most often cited and popularly accepted one. The Warring States era also overlaps with the second half of the Eastern Zhou dynasty, though the Chinese sovereign, known as the king of Zhou, ruled merely as a figurehead and served as a backdrop against the machinations of the warring states.  - Cao Cao (155  15 March 220), courtesy name Mengde, was a Chinese warlord and the penultimate Chancellor of the Eastern Han dynasty who rose to great power in the final years of the dynasty. As one of the central figures of the Three Kingdoms period, he laid the foundations for what was to become the state of Cao Wei and was posthumously honoured as "Emperor Wu of Wei". Although he is often portrayed as a cruel and merciless tyrant in subsequent literature, Cao Cao has also been praised as a brilliant ruler and military genius who treated his subordinates like his family. During the fall of the Eastern Han dynasty, Cao Cao was able to secure the most populated and prosperous cities of the central plains and northern China. Cao had much success as the Han chancellor, but his handling of the Han emperor Liu Xie was heavily criticized and resulted in a continued and then escalated civil war. Opposition directly gathered around warlords Liu Bei and Sun Quan, whom Cao was unable to quell. Cao was also skilled in poetry and martial arts and wrote many war journals.  - Vietnam, officially the Socialist Republic of Vietnam (SRV), is the easternmost country on the Indochina Peninsula in Southeast Asia. With an estimated 90.5 million inhabitants , it is the world's 14th-most-populous country, and the eighth-most-populous Asian country. Vietnam is bordered by China to the north, Laos to the northwest, Cambodia to the southwest, Thailand across the Gulf of Thailand to the southwest, and the Philippines, Malaysia and Indonesia across the South China Sea to the east and southeast. Its capital city has been Hanoi since the reunification of North and South Vietnam in 1976.  - Lady Zhen (26 January 183  4 August 221), personal name unknown, was the first wife of Cao Pi, the first ruler of the state of Cao Wei in the Three Kingdoms period. In 226, she was posthumously honoured as Empress Wenzhao when her son, Cao Rui, succeeded Cao Pi as the emperor of Wei.  - Cao Zhen (died 231), courtesy name Zidan, was a military general serving under the warlord Cao Cao in the late Eastern Han Dynasty. He served the state of Cao Wei during the Three Kingdoms period. He was also a distant nephew of Cao Cao, though the latter treated him like a son. Cao Zhen participated in many campaigns against the forces of Liu Bei and Sun Quan. From 227 onwards, he was very much involved with successfully repelling the frequent invasions led by Zhuge Liang.  - The nine rank system, or much less commonly nine grade controller system, was a civil service nomination system during the Three Kingdoms and the Southern and Northern Dynasties in China. Chen Qun, a court official of the Kingdom of Wei standardized its details.  - Zhuge Liang (181234), courtesy name Kongming, was a chancellor (or prime minister) and regent of the state of Shu Han during the Three Kingdoms period. He is recognised as the most accomplished strategist of his era, and has been compared to Sun Tzu, the author of "The Art of War". A self-avowed Legalist, he compared himself with Guan Zhong, developing Shu's agriculture and industry to become a regional power. He attached great importance to the works of Shen Buhai and Han Fei, refusing to indulge local elites and adopting strict, but fair and clear laws. In remembrance of his governance, local people maintained shrines to him for ages.
