There are several opinions about the construction time of the Hexi Great Wall in Wei State.

In the history of our country, there are two opinions about the construction time of the Great Wall in the west of Wei. One is that the Great Wall of Wei was built in 36 BC/KLOC-0 BC/Qin Benji. Another way of saying this is that the Great Wall of Wei was built in 352 BC, which is found in Wei He's Chronology of Six Kingdoms.

After research, relevant scholars believe that the first year of Qin Xiaogong mentioned in Qin Benji is closer to the truth.

Because, in ancient books, there is no record that Wei built the Great Wall in Hexi before the first year, which rules out the possibility of building the Great Wall before the first year. The rest may be that Wei built the Great Wall in the first year, otherwise there would be no such record.

In addition, the construction scale of the Great Wall in the west of Wei State is huge, and it is impossible to complete it within one year. Therefore, later generations think that the Great Wall should be built in the first year of Qin Xiaogong, and it lasted for 65,438+00 years.
