Question: When was the city that the spouse of Zhuo Lin died in made the capital of China?

<P0-S0> fearing sun jian, dong zhuo then sent his general li jue as an emissary to seek peace and propose a marriage to cement the alliance. <P0-S1> however, sun jian rejected the proposals with harsh words and continued to lead his troops towards luoyang. <P0-S2> in late 190, his army was merely 90 "li" away from the capital when dong zhuo retreated west to chang'an after ordering the destruction of luoyang by fire. <P0-S3> entering the ruins of luoyang, sun jian ordered his men to reseal the tombs of han emperors that were excavated by dong zhuo, after which he returned to luyang. <P0-S4> it was said in the "book of wu" (吳書) by wei zhao that sun jian found one of the emperor's jade seals in a well south of luoyang and kept it. <P0-S5> later, when yuan shu declared himself emperor, he held sun jian's wife lady wu hostage in exchange for the seal. <SEP> <P1-S0> nanjing ( listen; chinese: 南京, "southern capital") is the city situated in the heartland of lower yangtze river region in china, which has long been a major centre of culture, education, research, politics, economy, transport networks and tourism. <P1-S1> it is the capital city of jiangsu province of people's republic of china and the second largest city in east china, with a total population of 8,216,100, and legally the capital of republic of china which lost the mainland during the civil war. <P1-S2> the city whose name means "southern capital" has a prominent place in chinese history and culture, having served as the capitals of various chinese dynasties, kingdoms and republican governments dating from the 3rd century ad to 1949. prior to the advent of pinyin romanization, nanjing's city name was spelled as nanking or nankin. <P1-S3> nanjing has a number of other names, and some historical names are now used as names of districts of the city, and among them there is the name jiangning (江寧), whose former character jiang (江, river) is the former part of the name jiangsu and latter character ning (寧, simplified form 宁, peace) is the short name of nanjing. <P1-S4> when being the capital of a state, for instance, roc, jing (京) is adopted as the abbreviation of nanjing. <P1-S5> although as a city located in southern part of china becoming chinese national capital as early as in jin dynasty, the name nanjing was designated to the city in ming dynasty, about a thousand years later. <P1-S6> nanjing is particularly known as jinling (金陵, literally meaning gold mountain) and the old name has been used since the warring states period in zhou dynasty. <SEP> <P2-S0> Zhuo Lin (April 6, 1916 – July 29, 2009) was the third and last wife of Deng Xiaoping, former Paramount leader of China. <SEP> <P3-S0> The city of Beijing has a long and rich history that dates back over 3,000 years. <P3-S1> Prior to the unification of China by the First Emperor in 221 BC, Beijing had been for centuries the capital of the ancient states of Ji and Yan. <P3-S2> When Kublai Khan made Dadu the capital of the Mongol - led Yuan dynasty (1279 -- 1368), all of China was ruled from Beijing for the first time. <P3-S3> During the first millennia of imperial rule, Beijing was a provincial city in northern China. <P3-S4> Its stature grew in the 10th to the 13th centuries when the nomadic Khitan and forest - dwelling Jurchen peoples from beyond the Great Wall expanded southward and made the city a capital of their dynasties, the Liao and Jin. <P3-S5> From 1279 onward, with the exception of two interludes from 1368 to 1420 and 1928 to 1949, Beijing would remain as China's capital, serving as the seat of power for the Ming dynasty (1421 -- 1644), the Manchu - led Qing dynasty (1644 -- 1912), the early Republic of China (1912 -- 1928) and now the People's Republic of China (1949 -- present). <SEP> <P4-S0> It is commonly believed that this "big-character poster" directly targeted Chinese President Liu Shaoqi and senior leader Deng Xiaoping, who were then in charge of Chinese government's daily affairs and who tried to cool down the mass hysteria which had been coming into shape in several universities in Beijing since the May 16 Notice, through which Mao officially launched the Cultural Revolution, was issued.
