Question: What is the distance by bullet train between Shanghai and the city that used to be called Khanbaliq?

full_context: Document 1: Yuan dynasty: There were many religions practiced during the Yuan dynasty, such as Buddhism, Islam, and Christianity. The establishment of the Yuan dynasty had dramatically increased the number of Muslims in China. However, unlike the western khanates, the Yuan dynasty never converted to Islam. Instead, Kublai Khan, the founder of the Yuan dynasty, favored Buddhism, especially the Tibetan variants. As a result, Tibetan Buddhism was established as the de facto state religion. The top-level department and government agency known as the Bureau of Buddhist and Tibetan Affairs (Xuanzheng Yuan) was set up in Khanbaliq (modern Beijing) to supervise Buddhist monks throughout the empire. Since Kublai Khan only esteemed the Sakya sect of Tibetan Buddhism, other religions became less important. He and his successors kept a Sakya Imperial Preceptor (Dishi) at court. Before the end of the Yuan dynasty, 14 leaders of the Sakya sect had held the post of Imperial Preceptor, thereby enjoying special power. Furthermore, Mongol patronage of Buddhism resulted in a number of monuments of Buddhist art. Mongolian Buddhist translations, almost all from Tibetan originals, began on a large scale after 1300. Many Mongols of the upper class such as the Jalayir and the Oronar nobles as well as the emperors also patronized Confucian scholars and institutions. A considerable number of Confucian and Chinese historical works were translated into the Mongolian language.
Document 2: Beijing–Shanghai high-speed railway: Under former Minister of Railways Liu Zhijun, the railway line was the first one designed for a maximum speed of 380 km / h in commercial operations. The non-stop train from Beijing South to Shanghai Hongqiao was expected to finish the 1,305 kilometres (811 mi) journey in 3 hours and 58 minutes, averaging 329 kilometres per hour (204 mph), making it the fastest scheduled train in the world, compared to 9 hours and 49 minutes on the fastest trains running on the parallel conventional railway. But following Liu Zhijun's dismissal in February 2011, several major changes were announced. First, trains would be slowed to a maximum speed of 300 km / h (186 mph), reducing operating costs. At this speed, the fastest trains would take 4 hours and 48 minutes to travel from Beijing South to Shanghai Hongqiao, making one stop at Nanjing South. Additionally, a slower class of trains running at 250 km / h (155 mph) would be operated, making more stops and charging lower fares. On September 21, 2017, 350 km / h operation was restored with the introduction of China Standardized EMU, reducing travel times between Beijing and Shanghai to about 4 hours 30 minutes on the fastest scheduled trains.
Document 3: Qing dynasty: In addition to the six boards, there was a Lifan Yuan unique to the Qing government. This institution was established to supervise the administration of Tibet and the Mongol lands. As the empire expanded, it took over administrative responsibility of all minority ethnic groups living in and around the empire, including early contacts with Russia — then seen as a tribute nation. The office had the status of a full ministry and was headed by officials of equal rank. However, appointees were at first restricted only to candidates of Manchu and Mongol ethnicity, until later open to Han Chinese as well.
Document 4: Qing dynasty: By the mid-18th century, the Qing had successfully put outer regions such as Inner and Outer Mongolia, Tibet and Xinjiang under its control. Imperial commissioners and garrisons were sent to Mongolia and Tibet to oversee their affairs. These territories were also under supervision of a central government institution called Lifan Yuan. Qinghai was also put under direct control of the Qing court. Xinjiang, also known as Chinese Turkestan, was subdivided into the regions north and south of the Tian Shan mountains, also known today as Dzungaria and Tarim Basin respectively, but the post of Ili General was established in 1762 to exercise unified military and administrative jurisdiction over both regions. Dzungaria was fully opened to Han migration by the Qianlong Emperor from the beginning. Han migrants were at first forbidden from permanently settling in the Tarim Basin but were the ban was lifted after the invasion by Jahangir Khoja in the 1820s. Likewise, Manchuria was also governed by military generals until its division into provinces, though some areas of Xinjiang and Northeast China were lost to the Russian Empire in the mid-19th century. Manchuria was originally separated from China proper by the Inner Willow Palisade, a ditch and embankment planted with willows intended to restrict the movement of the Han Chinese, as the area was off-limits to civilian Han Chinese until the government started colonizing the area, especially since the 1860s.
Document 5: Nanjing: Among all 17 railway stations in Nanjing, passenger rail service is mainly provided by Nanjing Railway Station and Nanjing South Railway Station, while other stations like Nanjing West Railway Station, Zhonghuamen Railway Station and Xianlin Railway Station serve minor roles. Nanjing Railway Station was first built in 1968. In 1999, On November 12, 1999, the station was burnt in a serious fire. Reconstruction of the station was finished on September 1, 2005. Nanjing South Railway Station, which is one of the 5 hub stations on Beijing–Shanghai High-Speed Railway, has officially been claimed as the largest railway station in Asia and the second largest in the world in terms of GFA (Gross Floor Area). Construction of Nanjing South Station began on 10 January 2008. The station was opened for public service in 2011.
Document 6: Shanghai–Hangzhou high-speed railway: The Shanghai–Hangzhou high-speed railway (), also known as the Huhang high-speed railway or Huhang passenger railway is a high-speed rail line in China between Shanghai and Hangzhou, Zhejiang. The line is in length and designed for commercial train service at . It was built in 20 months and opened on October 26, 2010. The line shortened travel time between the two cities from 78 to 45 minutes. The line is also used by trains departing Shanghai's terminals for Nanchang, Changsha, Guiyang, and Kunming making it part of the Shanghai–Kunming High-Speed Railway. It has made the proposed Shanghai–Hangzhou Maglev Line unlikely.
Document 7: Tibet: Tibet retained nominal power over religious and regional political affairs, while the Mongols managed a structural and administrative rule over the region, reinforced by the rare military intervention. This existed as a "diarchic structure" under the Yuan emperor, with power primarily in favor of the Mongols. Mongolian prince Khuden gained temporal power in Tibet in the 1240s and sponsored Sakya Pandita, whose seat became the capital of Tibet. Drogön Chögyal Phagpa, Sakya Pandita's nephew became Imperial Preceptor of Kublai Khan, founder of the Yuan dynasty.
Document 8: Sino-Tibetan relations during the Ming dynasty: The official position of the Ministry of Foreign Affairs of the People's Republic of China is that the Ming implemented a policy of managing Tibet according to conventions and customs, granting titles and setting up administrative organs over Tibet. The State Council Information Office of the People's Republic states that the Ming dynasty's Ü-Tsang Commanding Office governed most areas of Tibet. It also states that while the Ming abolished the policy council set up by the Mongol Yuan to manage local affairs in Tibet and the Mongol system of Imperial Tutors to govern religious affairs, the Ming adopted a policy of bestowing titles upon religious leaders who had submitted to the Ming dynasty. For example, an edict of the Hongwu Emperor in 1373 appointed the Tibetan leader Choskunskyabs as the General of the Ngari Military and Civil Wanhu Office, stating:
Document 9: Nanjing: Nanjing is an important railway hub in eastern China. It serves as rail junction for the Beijing-Shanghai (Jinghu) (which is itself composed of the old Jinpu and Huning Railways), Nanjing–Tongling Railway (Ningtong), Nanjing–Qidong (Ningqi), and the Nanjing-Xian (Ningxi) which encompasses the Hefei–Nanjing Railway. Nanjing is connected to the national high-speed railway network by Beijing–Shanghai High-Speed Railway and Shanghai–Wuhan–Chengdu Passenger Dedicated Line, with several more high-speed rail lines under construction.
Document 10: Sino-Tibetan relations during the Ming dynasty: The Columbia Encyclopedia distinguishes between the Yuan dynasty and the other Mongol Empire khanates of Ilkhanate, Chagatai Khanate and the Golden Horde. It describes the Yuan dynasty as "A Mongol dynasty of China that ruled from 1271 to 1368, and a division of the great empire conquered by the Mongols. Founded by Kublai Khan, who adopted the Chinese dynastic name of Yüan in 1271." The Encyclopedia Americana describes the Yuan dynasty as "the line of Mongol rulers in China" and adds that the Mongols "proclaimed a Chinese-style Yüan dynasty at Khanbaliq (Beijing)." The Metropolitan Museum of Art writes that the Mongol rulers of the Yuan dynasty "adopted Chinese political and cultural models; ruling from their capitals in Dadu, they assumed the role of Chinese emperors," although Tibetologist Thomas Laird dismissed the Yuan dynasty as a non-Chinese polity and plays down its Chinese characteristics. The Metropolitan Museum of Art also noted that in spite of the gradual assimilation of Yuan monarchs, the Mongol rulers largely ignored the literati and imposed harsh policies discriminating against southern Chinese. In his Kublai Khan: His Life and Times, Rossabi explains that Kublai "created government institutions that either resembled or were the same as the traditional Chinese ones", and he "wished to signal to the Chinese that he intended to adopt the trappings and style of a Chinese ruler".
Document 11: Zhejiang: Ningbo, Wenzhou, Taizhou and Zhoushan are important commercial ports. The Hangzhou Bay Bridge between Haiyan County and Cixi, is the longest bridge over a continuous body of sea water in the world.
Document 12: High-speed rail: State planning for high - speed railway began in the early 1990s, and the country's first high - speed rail line, the Qinhuangdao -- Shenyang Passenger Railway, was built in 1999 and opened to commercial operation in 2003. This line could accommodate commercial trains running at up to 200 km / h (120 mph). Planners also considered Germany's Transrapid maglev technology and built the Shanghai Maglev Train, which runs on a 30.5 km (19.0 mi) track linking the city and its international airport. The maglev train service began operating in 2004 with trains reaching a top speed of 431 km / h (268 mph), and remains the fastest high - speed service in the world. Maglev, however, was not adopted nationally and all subsequent expansion features high - speed rail on conventional tracks.
Document 13: Beijing–Shanghai high-speed railway: The Beijing -- Shanghai High - Speed Railway (or Jinghu High - Speed Railway from its Chinese name) is a 1,318 - kilometre (819 mi) long high - speed railway that connects two major economic zones in the People's Republic of China, the Bohai Economic Rim and the Yangtze River Delta. Construction began on April 18, 2008, and a ceremony to mark the completion of track laying was held on November 15, 2010. The line opened to the public for commercial service on June 30, 2011. This rail line is the world's longest high - speed line ever constructed in a single phase. It is China's most profitable high speed rail line, reporting a 6.6 billion yuan net operational profit in 2015.
Document 14: Tibet: The Tibetan Empire emerged in the 7th century, but with the fall of the empire the region soon divided into a variety of territories. The bulk of western and central Tibet (Ü-Tsang) was often at least nominally unified under a series of Tibetan governments in Lhasa, Shigatse, or nearby locations; these governments were at various times under Mongol and Chinese overlordship. The eastern regions of Kham and Amdo often maintained a more decentralized indigenous political structure, being divided among a number of small principalities and tribal groups, while also often falling more directly under Chinese rule after the Battle of Chamdo; most of this area was eventually incorporated into the Chinese provinces of Sichuan and Qinghai. The current borders of Tibet were generally established in the 18th century.
Document 15: Yuan dynasty: The Central Region, consisting of present-day Hebei, Shandong, Shanxi, the south-eastern part of present-day Inner Mongolia and the Henan areas to the north of the Yellow River, was considered the most important region of the dynasty and directly governed by the Central Secretariat (or Zhongshu Sheng) at Khanbaliq (modern Beijing); similarly, another top-level administrative department called the Bureau of Buddhist and Tibetan Affairs (or Xuanzheng Yuan) held administrative rule over the whole of modern-day Tibet and a part of Sichuan, Qinghai and Kashmir.
