Question: Out of Changchun and Chengde, site of the huge Qing emperors' palace, which Chinese city had the largest population in 2010?
Context: The Changchun Film Festival is a biennial international film festival held in the Chinese city of Changchun.  Ostensibly international, its award for best film, the Golden Deer has nevertheless primarily been awarded to Chinese and other East Asia-region films.  It was first held in 1992 and was founded in part by the Changchun Film Studio (now the Changchun Film Studio Group Corporation). The imperial hunt of the Qing dynasty was an annual rite of the emperors of China during the Qing dynasty (1644–1911).  It was first organized in 1681 by the Kangxi Emperor at the imperial hunting grounds at Mulan, near what would become the summer residence of the Qing emperors at Chengde.  Starting in 1683 the event was held annually at Mulan during the autumn, lasting up to a month.  The Qing dynasty hunt was a synthesis of earlier Chinese and Inner Asian hunting traditions, particularly those of the Manchus and Mongols.  The emperor himself participated in the hunt, along with thousands of soldiers, imperial family members, and government officials. Imperial Chinese missions to the Ryukyu Kingdom were diplomatic missions which were intermittently sent by the Yuan, Ming and Qing emperors to Shuri, Okinawa in the Ryukyu Islands.  These diplomatic contacts were within the Sinocentric system of bilateral and multinational relationships in East Asia. The Putuo Zongcheng Temple () of Chengde, Hebei province, China is a Qing dynasty era Buddhist temple complex built between 1767 and 1771, during the reign of the Qianlong Emperor (1735–1796).  It is located near the Chengde Mountain Resort, which is south of the Putuo Zongcheng.  Along with the equally famed Puning Temple, it is one of the Eight Outer Temples of Chengde.  The temple was modeled after the Potala Palace of Tibet, the old sanctuary of the Dalai Lama built a century earlier.  Since it was modeled after the Potala palace, the temple represents a fusion of Chinese and Tibetan architectural styles.  The temple complex covers a surface area of some 220,000 m2 , making it one of the largest in China.  Many of its halls and pavilions are adorned with copper and gold tiled roofs, adding to the splendor of the site. Malanyu () is a town approximately 30 km west of the city of Zunhua, Hebei, China, which administrates the town.  It is the location of the final resting place of some of the Qing emperors and empresses. Chengde (), previously known as Jehol or Rehe, is a prefecture-level city in Hebei province, situated northeast of Beijing.  It is best known as the site of the Mountain Resort, a vast imperial garden and palace formerly used by the Qing emperors as summer residence.  The urban center had a population of approximately 450,000 as of 2009. Changchun () is the capital and largest city of Jilin Province, and is located in the northeast of China.  Lying in the center of the Songliao Plain, Changchun is administered as a , comprising 7 districts, 1 county and 2 county-level cities.  According to the 2010 census of China, Changchun had a total population of 7,674,439 under its jurisdiction.  The city's urbanized ("or metro") area, comprising 5 districts and 4 development areas, had a population of 3,815,270 in 2010 as the Shuangyang and Jiutai districts are not urbanized yet. The Mukden Palace (), or Shenyang Imperial Palace (), was the former imperial palace of the early Manchu-led Qing dynasty in China.  It was built in 1625 and the first three Qing emperors lived there from 1625 to 1644.  Since the collapse of imperial rule in China, the palace has been converted to a museum that now lies in the center of Shenyang city, Liaoning province. The National Palace Museum, located in Taipei and Taibao, Taiwan, has a permanent collection of nearly 700,000 pieces of ancient Chinese imperial artifacts and artworks, making it one of the largest of its type in the world.  The collection encompasses 8,000 years of history of Chinese art from the Neolithic age to the modern.  Most of the collection are high quality pieces collected by China's emperors.  The National Palace Museum shares its roots with the Palace Museum in the Forbidden City, whose extensive collection of artwork and artifacts were built upon the imperial collections of the Ming and Qing dynasties. Tibet under Qing rule refers to the Qing dynasty's rule over Tibet from 1720 to 1912.  During the Qing rule of Tibet, the region was structurally, militarily and administratively controlled by the Qing dynasty established by the Manchus in China.  In the history of Tibet, Qing administrative rule was established after a Qing army defeated the Dzungars who occupied Tibet in 1720, and lasted until the fall of the Qing dynasty in 1912, although the region retained a degree of political autonomy under the Dalai Lamas.  The Qing emperors appointed imperial residents known as the Ambans to Tibet, who commanded over 2,000 troops stationed in Lhasa and reported to the Lifan Yuan, a Qing government agency that oversaw the empire's frontier regions.  The protectorate that China had established over Tibet in the 18th century remained into the 20th century, but by the late 19th century Chinese hegemony over Tibet remained in theory but in actuality was a dead letter given the weight of China's domestic and foreign-relations burdens.  However, the Chinese began to take steps to reassert their authority shortly after the British expedition to Tibet.
