In Zhou Yiwang, White Tooth Kingdom presented three treasures: white parrot, cold and warm lamp and sober-up felt. At that time, Princess Su Ying was pregnant for three months, so she took Su Ying as the main palace and was in charge of the Three Treasures. Mei Fei, another concubine of the king of Iraq, was jealous, so she and her brother Melen made a plan. During the banquet, he deliberately damaged the three treasures, falsely accused him of dishonour, and turned his face to see the king of Iraq, and was granted the death penalty. Prime Minister Pango knew that he was innocent and wronged, so he died for his wife Li, who seemed to be his concubine. Send Su Fei to live with her nephew Su Jing. Su Fei gave birth to a prince on the way. Mei Fei speculated that Su Fei was not dead and ordered Melen to search Pan Fu, but found nothing. Send someone to kill again, but it's useless. Su Fei abandoned the prince for adoption by farmers. 13 years later, the mother and son finally reunited and wrote a letter to Pango. Pan Zheng mourned his wife and Su Hou, so he immediately wrote a letter to Chen Qingyi. Wang Sui welcomed Su Fei's mother and son back to the DPRK, succeeded the Prince, imprisoned Mei Fei and beheaded Melen.
