During the Northern and Southern Dynasties, the small countries in northern China were separated.In order not to be invaded by the powerful neighbor Northern Wei Dynasty, the King of Northern Yan dedicated his daughter Feng Juan to Tuoba Tao as his concubine.But this did not stop Tuoba Tao's ambition to expand territory. He successively attacked Daxia, Beiyan, and Beiliang, and unified the north.

Feng Tong, who harbored hatred for her family and country, secretly determined to destroy Wei and Fuyan.After Tuoba Tao's death, the royal family went through turmoil and Tuoba Jun succeeded to the throne. He was deeply in love with Feng Tie's niece Feng Yao'er and made her the queen against all objections.Influenced by Feng Tie, Feng Yao'er approached Tuoba Jun with the idea of ​​restoring the country, but was infected by Tuoba Jun's outstanding insight and broad mind, and finally gave up his obsession with restoring the country.

Unfortunately, Tuoba Jun died young and amid the turmoil of the court, Feng Yaoer became the staunch successor to her husband's political legacy.She eliminated the left and right attacks from the conservative forces of the Tuoba royal family and the old Yan restoration organization, firmly pursued the policy of national reconciliation, actively accepted Han civilization, and had an important impact on promoting the integration of various ethnic groups in the north.
