Passage: Tomic belonged to the first class of six Serbian pilots trained in France in 1912. In August 1914, he participated in the first aerial dogfight of the war, when he exchanged gunfire with an Austro-Hungarian plane over western Serbia. In the winter of 1915, during the Serbian Army's retreat across Albania to the Greek island of Corfu, he evacuated General Petar Bojovic from Scutari by plane, delivered mail by air and transported the Serbian Government's gold and hard currency reserves from Nis to keep them from falling into enemy hands. Following the occupation of Serbia by the Central Powers, Tomic went to France and flew over the Western Front, where he had one confirmed kill. He returned to the Balkans in late 1916, conducted combat missions over Bulgarian-occupied Macedonia and shot down one enemy plane. Tomic continued flying after the war and became head of the Royal Yugoslav Air Force's pursuit squadron in Novi Sad. During World War II, he was captured by the Germans and detained as a prisoner of war. Tomic left Yugoslavia following the war and settled in the United States with his wife. He died in Chicago in 1962.

Passage: About this time, some Dzungars informed the Kangxi Emperor that the 5th Dalai Lama had long since died. He sent envoys to Lhasa to inquire. This prompted Sangye Gyatso to make Tsangyang Gyatso the 6th Dalai Lama public. He was enthroned in 1697. Tsangyang Gyatso enjoyed a lifestyle that included drinking, the company of women, and writing love songs. In 1702, he refused to take the vows of a Buddhist monk. The regent, under pressure from the Emperor and Lhazang Khan of the Khoshut, resigned in 1703. In 1705, Lhazang Khan used the sixth Dalai Lama's escapades as excuse to take control of Lhasa. The regent Sanggye Gyatso, who had allied himself with the Dzungar Khanate, was murdered, and the Dalai Lama was sent to Beijing. He died on the way, near Kokonor, ostensibly from illness but leaving lingering suspicions of foul play. Lhazang Khan appointed a new Dalai Lama who, however, was not accepted by the Gelugpa school. Kelzang Gyatso was discovered near Kokonor and became a rival candidate. Three Gelug abbots of the Lhasa area appealed to the Dzungar Khanate, which invaded Tibet in 1717, deposed Lhazang Khan's pretender to the position of Dalai Lama, and killed Lhazang Khan and his entire family. The Dzungars proceeded to loot, rape and kill throughout Lhasa and its environs. They also destroyed a small force in the Battle of the Salween River which the Emperor had sent to clear traditional trade routes.
Link Information: The Battle of the Salween River was fought in September 1718 close to the Nagqu(i.e., Salween River) in Tibet, between an expedition of the Qing dynasty to Lhasa and a Dzungar Khanate force that blocked its path. Question: Who did the Dzungars oppose in while clearing trade routes?

Ex Output:
Answer: Qing dynasty
