Sui and Tang Dynasties: At the beginning, Mrs. Li ran away from relatives

Once crossing, Cao Feng met the upcoming engagement banquet, but Li Xiuning escaped two days ago.
Cao Feng made an engagement with his eldest grandson Wugou directly, and held a banquet as scheduled to avoid being the laughing stock of others.
His father, Li Yuan, came to the door to apologize, plus the so-called compensation, trying to expose the matter.
If an apology is useful, then why do we need the law?
Li Xiuning: It is clear that the queen of the world is my mother, and the heroes of the world belong to me. I regret it!
Li Yuan: Finally, I understand my father's last words. I can't offend the generation of the Cao family. It turns out that it is the emperor's family.
