In Tuoketuo County under the jurisdiction of Hohhot, the capital of the Inner Mongolia Autonomous Region, there is the Yunzhong Jinling, a group of royal mausoleums in the early Northern Wei Dynasty. The erosion of the years has long made the mausoleum dilapidated, but you can still feel a certain majesty of silence. This is also the resting place of our protagonist, Tuoba Si, Emperor Mingyuan of the Northern Wei Dynasty. Compared with Tuoba Tao, the Taiwu Emperor who drank from the Yangtze River and was powerful in the north and south, and Tuoba Hong, the Xiaowen Emperor who changed customs and moved the capital to Luoyang, Tuoba Si's existence seems much dimmer. However, when the afterglow of the setting sun falls on this barren land, it seems to be silently telling the life of this emperor. Let us set aside the dust of history and go back to the turbulent years when the Northern Wei Dynasty was founded, to the era of iron horses and glacial rivers and long-lasting love between sons and daughters.
