Why did zhu yuanzhang enlarge the chinese army

The military of the Ming dynasty was the military apparatus of China from 1368 to 1900 It was founded in 1368 during the Red Turban Rebellion by the Ming founder Zhu Yuanzhang. The military was initially organised along largely hereditary lines and soldiers were meant to serve in self-sufficient agricultural communities. They were grouped into guards (wei) and battalions (suo), otherwise known as the wei-suo system. This hereditary guard battalion system went into decline around 1450 and was discarded in favor of mercenaries a century later.

Explanation: The Ming emperors from Hongwu to Zhengde continued policies of the Mongol-led Yuan dynasty such as hereditary military institutions, dressing themselves and their guards in Mongol-style clothing and hats, promoting archery and horseback riding, and having large numbers of Mongols serve in the Ming military. Until the late 16th century Mongols still constituted one-in-three officers serving in capital forces like the Embroidered Uniform Guard, and other peoples such as Jurchens were also prominent.[1][2] A cavalry-based army modeled on the Yuan military was favoured by the Hongwu and Yongle Emperors.[3]Contrary to the stereotype that the Confucian Ming were disinterested in the military, the Ming poured enormous resources such as landholdings into upkeeping its military, which also constituted the biggest portion of the state budget. The Ming deliberately placed the military and civilian officials in opposition to each other for checks and balances. Troops often feuded, looted, evaded tax or resisted law enforcement in defiance of civilian officials, prompting the court to place civilian officials to supervise the military.[4]At the Guozijian Academy, equestrianism and archery were emphasized by the Hongwu Emperor in addition to Confucian classics, also being required in the Imperial Examinations.[5][6]: 267 [7][8][9][10] Archery and equestrianism were added to the exam by Hongwu in 1370 just as archery and equestrianism were required for non-military officials at the College of War (武舉) in 1162 by Emperor Xiaozong of the Song dynasty.[11]
