In early May 1935, Chiang Kai-shek, Feng Yuxiang and Yan Xishan started a big battle in the Central Plains. Feng Yuxiang and Yan Xishan had agreed to meet at Qinyang in the northern part of Henan Province in order to concentrate their forces to annihilate Chiang's troops stationed in Henan Province for the sake of better combating Chiang. Unfortunately, in the preparation of the order, one of Feng Yuxiang's operational staff wrote the word "qin" in "qinyang" as "uyang". It so happens that there is a Uyang in the south of Henan, but this place is thousands of miles away from Qinyang. Feng Yuxiang's troops received the order to rush to Uyang, the result was a missed opportunity to miss the favorable opportunity to annihilate Chiang's army, so that Chiang's army gained the initiative. In the nearly half a year of the Great War in the Central Plains, Feng and Yan allied forces were passive and beaten at every turn. A word difference, ultimately leading to Feng, Yan allied forces in the Central Plains battlefield comprehensive failure.
