Idiom story

The allusion of "in the morning of Qin and in the evening of Chu" recorded in historical books is in jingziguan, the border of Henan and Shaanxi - "about 5 kilometers up the Danjiang River, you come to a place called Yueliangwan. At the junction of Henan and Shaanxi, there is a pass where the two mountains confront each other. Outside the pass is Qinchuan, 800 Li; inside the pass is the open central plains. The roaring Danjiang River and the narrow ancient road together build a "one man is the gateway, ten thousand men are not allowed to open" pass here. This pass is the "pass" of Jingzi pass. This is the name of jingziguan. This pass is the second legend of Jingzi pass. There is a dangerous pass across here. How many wars have happened since ancient times can only be explained clearly by the green mountains and green waters. According to historical records, the most influential war in the early jingziguan period should be the "Danyang war" between Qin and Chu. During the Warring States period, wars between Qin and Chu were frequent. At that time, jingziguan was the junction of the state of Qin and the state of Chu, some of which belonged to the state of Qin, and some belonged to the jurisdiction of Danyang county. In 312 BC, the battle of Danyang broke out between the state of Qin and the state of Chu. After the victory of the state of Qin, jingziguan belonged to the territory of the state of Qin. After that, the Qin and Chu countries were rebuilt, and the state of Qin assigned this place to the state of Chu. There is an idiom called "morning Qin and evening Chu". The explanation in modern Chinese dictionary is: incline to the state of Qin at one time, and attach to the state of Chu at another time, which means people are capricious. Few people know that the source of this allusion is jingziguan
