Problem: Andriana refers to both the noble class and a title of nobility in Madagascar. Historically, many Malagasy ethnic groups lived in highly stratified caste-based social orders in which the andriana were the highest strata. They were above the Hova (free commoner castes) and Andevo (slaves). The Andriana and the Hova were a part of Fotsy, while the Andevo were Mainty in local terminology.

Austronesian people started settling in Madagascar between 200 to 500 CE. They arrived by boats and were from various southeast Asian groups. African slaves were brought to the island's coasts between the 13th and the 18th centuries. The Portuguese traders were the first Europeans to arrive in the 15th century, followed by other European powers. This influx of diverse people led to various Malagasy sub-ethnicities in the mid-2nd millennium. The Merina were probably the early arrivals, though this is uncertain and other ethnic groups on Madagascar consider them relative newcomers to the island. The Merina people's culture likely mixed and merged with the Madagascar natives named Vazimba about whom little is known. According to the island's oral traditions, the "most Austronesian looking" Merina people reached the interior of the island in the 15th century and established their society there because of wars and migrant pressure at the coast. Merina people were settled in the central Madagascar, formed one of the three major kingdoms on the island by the 18th century - the other two being Swahili-Arab influenced Sakalava kingdom on the west-northwest and Austronesian Betsimisaraka kingdom on the east-northeast. The term Hova originally applied to all members of the Merina people who arrived in the central highlands around the 15th century and absorbed the existing population of Vazimba. Andriamanelo (1540-1575) consolidated the power of the Hova when he united many of the Hova chiefdoms around Antananarivo under his rule. The term Hova remained in use through the 20th century, though some foreigners transliterated that word to be Ankova, and increasingly used since the 19th century. In and after the 16th century, slaves were brought into Madagascar's various kingdoms, and social strata emerged in Merina kingdom. The Hova emerged as the free commoners caste below the nobles hierarchy. During the rule of King Andriamanelo, a subset of Hova related to the king by blood came under the title Andriana. The social structure of the new kingdom became further defined under his son Ralambo (1575-1612), who further subdivided the Andriana into four ranks, and eventually six sub-castes by King Andriamasinavalona (1675-1710).

Problem: Xi Jinping (; Chinese: Xi Jin Ping ; pinyin: Xi Jinping; born 15 June 1953) is a Chinese politician currently serving as General Secretary of the Communist Party of China, President of the People's Republic of China, and Chairman of the Central Military Commission. As Xi holds the top offices of the party, the state, and the military, he is sometimes referred to as China's "paramount leader"; in 2016, the party officially gave him the title of "core" leader.

Xi Jinping was born in Beijing on 15 June 1953. After the founding of the People's Republic of China in 1949 by Mao Zedong, Xi's father held a series of posts, including propaganda chief, vice-premier, and vice-chairman of the National People's Congress. Xi's father is from Fuping County, Shaanxi, and Xi could further trace his patrilineal descent from Xiying in Dengzhou, Henan. He is the second son of Xi Zhongxun and his wife Qi Xin. In 1963, when Xi was age 10, his father was purged from the Party and sent to work in a factory in Luoyang, Henan. In May 1966, Xi's secondary education was cut short by the Cultural Revolution, when all secondary classes were halted for students to criticise and fight their teachers. The Xi family home was ransacked by student militants and one of Xi's sisters, Xi Heping, was killed. Later, his own mother was forced to publicly denounce him as Xi was paraded before a crowd as an enemy of the revolution. Xi was aged 15 when his father was imprisoned in 1968 during the Cultural Revolution; Xi would not see his father again until 1972. Without the protection of his father, Xi was sent to work in Liangjiahe Village, Wen'anyi Town, Yanchuan County, Yan'an, Shaanxi, in 1969 in Mao Zedong's Down to the Countryside Movement. After a few months, unable to stand rural life, he ran away to Beijing. He was arrested during a crackdown on deserters from the countryside and sent to a work camp to dig ditches. He later became the Party branch secretary of the production team, leaving that post in 1975. When asked about this experience later by Chinese state television, Xi recalled, "It was emotional. It was a mood. And when the ideals of the Cultural Revolution could not be realised, it proved an illusion." From 1975 to 1979, Xi studied chemical engineering at Beijing's prestigious Tsinghua University as a "Worker-Peasant-Soldier student", where engineering majors spent about one-fifth of their time studying Marxism-Leninism-Mao Zedong thought, doing farm work and "learning from the People's Liberation Army". From 1979 to 1982, Xi served as secretary for his father's former subordinate Geng Biao, the then vice premier and secretary-general of the Central Military Commission. This gained Xi some military background. In 1985, as part of a Chinese delegation to study U.S. agriculture, he stayed in the home of an American family in the town of Muscatine, Iowa. This trip, and his two-week stay with a U.S. family, is said to have had a lasting impression upon him and his views on the United States. From 1998 to 2002, he studied Marxist philosophy and ideological education in an "on-the-job" postgraduate programme at the School of Humanities and Social Sciences, again at Tsinghua University, and obtained a Doctor of Law (LLD) degree, which was a degree covering fields of law, politics, management, and revolutionary history, though commentators have questioned this qualification.
