In Song Dynasty, two pregnant women gave birth on the same day in the Anpinghou Mansion. The concubine Su Jinyun gave birth to Li Baoer, the misfortune star, using medicine first, and the wife Zhou Shulan later gave birth to Li Yuanyue, the ninth princess who has experienced tribulations in the immortal world. Su Jinyun used the bought son to bring about the misfortune of her own birth. The emperor mistakenly believed that the colorful auspicious clouds in the sky when Li Yuanyue was born belonged to Su Jinyun's son, so he named Su Jinyun's bought son Tian Jingrui. From then on, a series of entanglements and disputes arose between the three children.
