The Fengtian clique's Zhili Army was a Chinese Warlord Era fighting force that controlled the Republic of China's Zhili province from 1924 until 1928, with the exception of a few months in 1925/26. Not related to the Zhili clique, it instead originated as Fengtian Second Army and operated as part of the Fengtian clique's armed forces. It was led by two successive Fengtian warlords, Li Jinglin and Chu Yupu, who always followed the orders of Zhang Zuolin, the Fengtian clique's overall leader. Although the Zhili Army's quality declined after 1925, it distinguished itself in numerous battles until it was disbanded in 1928 after being defeated by the National Revolutionary Army in the Northern Expedition.

Li Jinglin, also known as Li Fangchen (1885–1931) was a deputy inspector-general and later army general for the Fengtian clique during the Chinese warlord era. He hailed from Zaoqiang County, Hebei province, China. After his military career was over he settled in Nanjing, and in 1927 moved to Shanghai. A renowned swordsman, he was known as "China's First Sword."
