Everyone in the capital knew that the eldest princess Tang Wan had a cold-faced husband, the "Jade-faced Shura" Lu Chen. He taught her to recite "There is a beautiful person, pure and graceful", but when she asked for marriage, he coldly refused. She was disheartened and he left the border. Three years later, her father died suddenly and her younger brother ascended the throne. She was forced to marry the Huns. On the day of sending off the bride, the border was filled with yellow sand. Lu Chen, who had already become a highly respected official, stopped him on his own and tore up the patriotic letter in public. "Go back and tell you Shanyu——" "Tang Wan is Lu's unmarried wife." Later, he broke into the Huns' court and exchanged his immortal military exploits for a marriage decree. On the wedding night, he pressed his forehead against hers and asked in a hoarse voice: "Your Highness, do you know why I didn't dare to respond back then?" "Because I was afraid that I wouldn't be able to protect you." "Now, with the country as the betrothal and the world as the witness - is Your Highness still willing to marry me?"
