Based on the epic couple in history, Emperor Wen of Sui and his wife. After founding the Sui Dynasty, Yang Jian (Chen Xiao) and Dugu Qieluo (Chen Qiao En) initiated several economic, agricultural and political reforms that enabled the dynasty to enter a new golden age. Unfortunately, the couple’s legacy would later be ruined by their son Emperor Yang. Unlike most royal couples in history, this pair was truly in love. Yang Jian would permanently reside in his Queen's palace (against traditional custom), and all of his children were borne by Dugu Qieluo. He only had four concubines in his inner palace, and most of them were created after Dugu Qieluo’s death in 602.
