Tuman City, originally known as Tuman City.
The history of Yan State, if the most recent hundred years are removed, is largely a war chronicle of battles with the barbarians. During the war years, Tuman City was the frontline of the battle between Yan State and the barbarian tribes.
Countless times, men of Yan State marched from here to the desert.
Either they were wrapped in horse leather in death, or they triumphantly brought back the heads of the barbarians.
A significant reason the kingdoms of the Central Plains were such failures was that Yan State, using its own strength, blocked the Northern threat from the desert, giving the three major kingdoms of the Central Plains a chance to "sing and dance."
Of course, it is not to say that the successive monarchs of Yan State were so selflessly dedicated, willingly defending the border for the civilization of the Central Plains.
Who could blame them for their poor geographical location?
