After hundreds of years of purges, mainly after experiencing domestic political struggles, finally, in the sixth year of the Great Qi Dynasty, the new Nanyi king agreed to pay homage and marry his legitimate princess, Yuehua. Emperor Daqi Ming was overjoyed and granted Princess Yuehua the title of noble concubine and the title "He".
The following year, he and his concubine died in childbirth, leaving behind a son. The king and queen of Yi were extremely sad when they heard the news, so they went to Jianglin, the imperial capital of Daqi, to see their beloved daughter off. Unexpectedly, when the Queen of Yi Kingdom visited her grandson, her personal maid found out and the young prince's wet nurse was poisoned. The poison is colorless and odorless and harmless to adults, but it can accumulate in the body of the little prince through breast milk and, over time, will lead to early death. The king and queen of Nanyi were furious and believed that if someone tried to kill his grandson, his daughter would definitely die. In the Jinluan Palace, Queen Nanyi spit on Emperor Ming. King Nanyi broke his sword and swore an oath to destroy Nanyi in mourning for Daqi. In order to appease the king and queen of Nanyi and avoid fighting, Emperor Ming first conducted a thorough investigation of the harem and investigated and punished hundreds of people. All the virtuous concubines who were born in the five princes of the first dynasty were mourned; The King and Queen of Nanyi finally compromised and left behind a Yi tribe voodoo girl named Chong Nan, who was considered an adopted daughter to raise the young prince. Emperor Ming showed his respect and granted Chongnan the title of concubine and the title of "righteousness".
