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.
