How did the conflict with the Gurkhas of Nepal end in 1792?

The conflict between the Qing dynasty and the Gurkhas of Nepal (1790–1792) concluded after the Qing military commander Fukang’an led an expedition into Tibet to repel the invading forces.12

Despite operating on unfamiliar territory far from his supply lines in Beijing, Fukang’an successfully defeated the Gurkha army. He drove them back across the high plateaus into their homeland in Nepal, effectively ending the incursions on the Tibetan frontier. Following this defeat, Nepal agreed to become a tributary state and committed to paying regular tribute to the Qing capital.12
