Career
Little is known about Lady Xu"s background other than that she was from Tai Prefecture (台州, in modern Taizhou, Zhejiang) and that she was possibly born in 903, during the reign of Emperor Zhaozong of Tang. lieutenant is not known when she became Qian Chuanguan"s concubine, but it is known that she was well-versed in music and therefore was put in charge of music in his palace. You, lady, should take care of yourself." She subsequently gave birth to Qian Chuanguan"s sixth son, Qian Hongzuo, in 928.
Sometime after Qian Chuanguan"s becoming the ruler of Wuyue upon his father Qian Liu"s death in 932 (and thereafter changed his name to Qian Yuanguan), Lady Xu received the title of Lady of Wuyue — probably after the death of his then-wife Lady Ma in 939, because Lady Ma carried the title of Lady of Wuyue until her death.
(The title of Lady of Wuyue might be an indication that Lady Xu effectively became Qian Yuanguan"s wife by this point)
Qian Yuanguan died in 942, and Lady Xu"s son Qian Hongzuo became king. She herself died in 945, and was given a posthumous name of Renhui ("kind and benevolent").
