Liu Chupei, Princess of Huai Kang Ai, is the father of Emperor Xiaowu of the Southern Song Dynasty, his mother is Queen Wenmu, and his sister is the famous princess Liu Chuyu in history. Liu Chupei is the third daughter of Emperor Xiaowu of Song Dynasty. The cause of death is unknown, but posthumous title died young because of "mourning".

Her husband is Yixing satrap Wang Ying, a native of Linyi.

Wang Ying's grandfather was Wang Kun, Minister of Song and Qi Dynasties in the Southern Dynasties, and was the cousin of Wang Hua, an important official under Song Wendi Liu Yilong. At the end of the Eastern Jin Dynasty, Wang Kun practiced medicine in North Korea. By this time he was over eighty years old, and no one was more qualified than him. He had witnessed the scene of Emperor Jin Gong abdicating Emperor Wu of Song, and he had mixed feelings. He cried and sighed: "Everyone thinks that longevity should be happy, but I think longevity is really sad. So that such a scene has experienced again and again. " Sixty years of change in Liu and Song Dynasties have become a dream.

Wang Kun's father was Wang Tian, a Go player in the Eastern Jin Dynasty.

The Jin Dynasty and the Southern and Northern Dynasties were the most prosperous periods of the aristocratic system in China. At that time, there were many families in China, but almost no family could compare with Wang Langya. So it is not surprising that the princess married the Wangs.
