She is the princess of a subjugated country, who has become an acrobatic musician incognito. She has a bit of cinnabar between her eyebrows, and is both beautiful and talented. He was the son of a general from the previous dynasty, and he was dormant in the new dynasty, plotting to restore the country and take revenge. The two met on the west bank of the painting building. She played the pipa, while he was distracted and secretly in love.
He offered her a job with the country and promised her a post after the restoration of the country. However, there was a mutiny and he came to the city, but because of her (being held hostage), "the six armies did not move". In order not to become his weakness, she wore seven layers of wedding clothes and committed suicide on the city tower with the dagger he gave her, staining the white gauze with her blood.
He finally broke through the city, but only saw her body. For many years after that, he ruled the world, and because of that hexagram back then, "it was for her that he conquered the world." He searched for the alchemist all over the place, just to meet her again in his dream, but when he woke up, he only found the room full of loneliness.
Purpose: The author wants to write a poignant story about the revenge of a princess who lost her country.
