During the Spring and Autumn Period and the Warring States Period, the Wei State was sandwiched between Qi, Qin, Chu and Zhao, and the geographical location was not dangerous to defend, but Wei Wenhou of Wei State, as an enlightened monarch, recruited talents in many ways, and under his effective governance, the strength of the Wei army was quite strong. The selection criteria of Wei Wushu: Carry a sword, carry an iron-tired hard bow and fifty arrows on his back, carry three days of military rations, and march a hundred miles in half a day. Once selected as Wei Wushu, you can enjoy preferential treatment. The combat effectiveness of such a unit can be imagined.
In 389 BC, the Battle of Yin and Jin broke out. Qin raised 500,000 troops to the east, and Wu Qi met the enemy with 50,000 Wei troops. According to the situation of the enemy's large number of people, Wu Qi worked out the deployment of concentrating superior forces to fight a war of annihilation, and he himself set an example and rushed to the front line. As a result, 500,000 Qin troops were beaten by 50,000 Wei troops and collapsed, and corpses were everywhere. There are not many expensive soldiers, and a good general is indispensable.
