The Shengwu Emperor of the Later Wei bore the family name Tuoba and the first name Jiefen. Once, when he was hunting in the mountains and marshes he saw a beautiful woman riding in a curtained carriage and descending from the heavens. On her arrival, she emerged and said: “I am a daughter of the heavens, and have been ordered to come and marry Your Lordship.” The following morning she addressed the emperor: “Having combined with Your Lordship I am now with child; after a year has passed I will return here.” Having spoken, she departed. The following year, the emperor went there on time, and the daughter of heaven arrived as promised, handing over the child she had borne to the emperor, saying: “This is Your Lordship’s child, and will produce a line of emperors and princes.” After speaking she departed. The emperor named his son Li Wei, and he became the Shenyuan Emperor, the first imperial ancestor of the Wei. People of the time said: “Emperor Jifen lacked wife and family, Emperor Liwei lacked maternal uncles.” This is truly a marvel!”
