As the first and only daughter of an emperor who was forced to marry due to defeat in the Han Dynasty, the delicate Princess Nangong was sent to the Huns as a victim of the power struggle. The humiliation and trampling she suffered were unimaginable. However, such a princess, deep in the desolate desert, could still impress her two husbands with her perseverance, calmness and magnanimity. Her predecessor treated her like a daughter, and her successor loved her more than the country. Until her later years, she told her children and grandchildren about her life. She said that she had never regretted it. Even though she had experienced a darkness as terrible as hell in the first half of her life, she broke through all obstacles and persisted bloody until the end. She also got the most beautiful rainbow as she wished.
