During the Qing Dynasty, Tsarist Russia began to embezzle Chinese territory. In particular, Tsar Russia colluded with the grassland wolf of Girdan. Ghardan attempted to overthrow the Qing Dynasty. Tsarist Russia took the opportunity to invade China's land. At that time, the Emperor Kangxi wanted to solve the problem as soon as possible. The insurgency of the Zhungar Department thus made great concessions in the process of negotiations with Tsarist Russia. The signing of the "Nabhu Treaty" had ceded the Sino-Russian border in the area east of Lake Baikal.
