Qing Dynasty was the Northern Zhou Dynasty of the Northern Dynasties. "Celebrating the country" is a fictional dynasty, which does not exist in history. However, according to the TV series, the Qing Dynasty should be the Northern Zhou Dynasty in the Wei, Jin, Southern and Northern Dynasties.

According to the time point, after 420 A.D., the real enemy of "Northern Qi" in history should be Northern Zhou, so the historical prototype of "Southern Qing" should be Northern Zhou;

According to the national strength, the national strength of the Southern Dynasties was much higher than that of the Northern Dynasties and the Northern Qi Dynasty. However, in real history, although the Northern and Southern Dynasties experienced several rounds of regime change, the strength of the Northern Dynasty was always above that of the Southern Dynasty. If we sit in the right place according to national strength, the Northern Qi is still the Northern Qi of the Northern Dynasties, while the Qing Dynasty is more like the Northern Zhou of the Northern Dynasties.

The surnames of the protagonists in national TV dramas are inferred: the Northern Zhou Dynasty was replaced by the Sui Dynasty, and the Sui Dynasty was replaced by the Tang Dynasty. The royal family in the Tang Dynasty was Li. The name of Prince Di Qing is Li Chenggan, which is the same as that of Prince Li Chenggan of Emperor Taizong of Li Shimin. It can be seen that the background of TV series is a mirror image of the history of the Southern and Northern Dynasties and the early years of Sui and Tang Dynasties.
