On the way to the Long March, the Red Army joined forces five times, namely Mao Gong, Yongping, Wuqi, Ganzi and Huining. Wu Qi joined forces with the Red Army in northern Shaanxi. Wuqi is located in the middle of Wuqi County in the northwest of Yan 'an City, Shaanxi Province. According to legend, Wu Qi, a general of Wei State, was stationed here during the Warring States Period, hence the name. 1In September, 936, the Red Army crossed the Snow Mountain and Minshan Grassland; 16 crossed Liupanshan and arrived in Wuqi; 19 joined forces with the Red Army in northern Shaanxi. After arriving in Wuqi, he called Peng on the same day: "Wuqi is already the border of the Soviet Union, and there is a red regime to the east of this place. There is a Red Army in Baoan City, but there are more than 100 landlords in Jinfoping between Wuqi and Jintang Town, and it is planned to send a team to destroy it. "
