Textual research on the address of Hanguguan

There are two monuments named after Hanguguan: Qin Guan is located in Wang Duo Village, which is15km north of lingbao city, and about 75km away from Sanmenxia City, which is called Jiuguan in history; Han Guan moved eastward to Xin 'an County, Luoyang, west of Qin Guan150km, which was called Xin Guan in history. The Hangu Pass we are talking about now generally refers to the old pass, that is, the Qin Pass.

After the establishment of the Western Han Dynasty, the world was unified and lasted for a long time. The status of Hanguguan has also become less important. At the beginning of the Han Dynasty, a captain was appointed to guard it. During the period of Emperor Wu of the Han Dynasty, Yang Fu was pacified on the balcony. He didn't ask for other rewards because of his great achievements, but offered to be a wife in Hanguguan. Yang Fu, a native of Xin 'an, Henan Province, was outside Shanhaiguan (this requirement is similar to asking the emperor to give him and his hometown a capital account).

Emperor Wu of the Han Dynasty listened to Yang's request, but the emperor did not move all the people in Xin 'an to the capital, but "moved to the eastern boundary of Xin 'an (now Xin 'an County, Henan Province), taking Guguan as hongnong county and governing hongnong county." Is ordered to move the old kanto east of Xin' an county, that is, to move the old customs Qin kanto about 300 Li. So there was the origin of the old and new Hangu Pass.

The new pass is located at the eastern end of the mountain, although it also has the function of controlling traffic, but its importance is far less than that of the old Qin pass Hanguguan.
