Question: When was You Quan's birthplace made the capitol of China?

full_context: Document 1: History of the Forbidden City: The site of the Forbidden City was situated on the Imperial city during the Mongol Yuan Dynasty. After the collapse of the Yuan Dynasty, the Hongwu Emperor of the Ming Dynasty moved the capital from Beijing in the north to Nanjing in the south, and in 1369 ordered that the Yuan palaces be razed. His son Zhu Di was created Prince of Yan with his seat in Beijing. In 1402, Zhu Di usurped the throne and became the Yongle Emperor. He made Beijing a secondary capital of the Ming empire, and construction began in 1406 of what would become the Forbidden City. The Forbidden City's plan was designed by many architects and designers, and then it was examined by the Emperor's Ministry of Work. The chief architects and engineers include Cai Xin, Nguyen An, a Vietnamese eunuch, Kuai Xiang, Lu Xiang and others.

Document 3: Yuan dynasty: Kublai readied the move of the Mongol capital from Karakorum in Mongolia to Khanbaliq in 1264, constructing a new city near the former Jurchen capital Zhongdu, now modern Beijing, in 1266. In 1271, Kublai formally claimed the Mandate of Heaven and declared that 1272 was the first year of the Great Yuan (Chinese: 大元) in the style of a traditional Chinese dynasty. The name of the dynasty originated from the I Ching and describes the "origin of the universe" or a "primal force". Kublai proclaimed Khanbaliq the "Great Capital" or Daidu (Dadu, Chinese: 大都 in Chinese) of the dynasty. The era name was changed to Zhiyuan to herald a new era of Chinese history. The adoption of a dynastic name legitimized Mongol rule by integrating the government into the narrative of traditional Chinese political succession. Khublai evoked his public image as a sage emperor by following the rituals of Confucian propriety and ancestor veneration, while simultaneously retaining his roots as a leader from the steppes.
Document 4: Liang Congjie: Liang's father, architect Liang Sicheng, had led attempts to prevent the destruction of the walls surrounding Beijing with the land to be used for the construction of highways. His grandfather Liang Qichao spent 14 years in exile in Japan after he advocated on behalf of turning the Qing Dynasty into a constitutional monarchy. His ancestry came to haunt him during the Maoist Cultural Revolution when he was purged for his being the "grandson of China's biggest royalist". Liang was ultimately able to attend Peking University.
Document 5: Qing dynasty: First, the Manchus had entered "China proper" because Dorgon responded decisively to Wu Sangui's appeal. Then, after capturing Beijing, instead of sacking the city as the rebels had done, Dorgon insisted, over the protests of other Manchu princes, on making it the dynastic capital and reappointing most Ming officials. Choosing Beijing as the capital had not been a straightforward decision, since no major Chinese dynasty had directly taken over its immediate predecessor's capital. Keeping the Ming capital and bureaucracy intact helped quickly stabilize the regime and sped up the conquest of the rest of the country. However, not all of Dorgon's policies were equally popular nor easily implemented.
Document 6: History of Beijing: The city of Beijing has a long and rich history that dates back over 3,000 years. 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. During the first millennia of imperial rule, Beijing was a provincial city in northern China. 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. 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. 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).
