A Different Three Kingdoms, Starting with the Prince of Daxia

The protagonist has an imperial-Han mentality. The book mentions many times that the Song people captured from the Central Plains were both officials and craftsmen. The Khitan party Xiang Duxiang was a reckless man who only knew how to wield swords and guns. Song soldiers were also reused. The Song soldiers were very good at defending the city. Aren't Dang Xiang and the Khitan very good at defending the city? Did Zhao Er defeat Youzhou? Besides, defending and attacking the city relied on courage and endurance. It is recorded in the books of the Song Dynasty that the Jurchens were not afraid of death, had extraordinary courage and amazing endurance. No matter how many times they charge with casualties, they will not be defeated and the formation will be chaotic (the first generation Jurchen). Furthermore, the concept of nationalism arose in the 18th century and reached its peak in the 19th century before reaching the beginning of the 20th century. In the past, people were struggling to survive and only had class antagonism. There was no nationality. For example, after the Yuan Dynasty fell, many local officials fled north with Emperor Shun of the Yuan Dynasty, and some of them died for their country. For example, in the Northern Song Dynasty, people lost their families and became party members but remained loyal to the Northern Song Dynasty. And the Khitan who surrendered turned to fight with their hometown Daliao. There are no ethnic conflicts, only class conflicts. I don't know why your book always emphasizes the Han people. Han people are educated when they are officials, but the Khitan party items are uneducated? Can't they be officials? Daliao and Khitan both have imperial examinations, both have scholar-bureaucrats and have cultural heritage, so why are they all barbarians and uneducated?
