Question: Who is the father of Lady Xu Xinyue's spouse?

full_context: Document 1: Qing dynasty: In 1725 Yongzheng bestowed the hereditary title of Marquis on a descendant of the Ming dynasty Imperial family, Zhu Zhiliang, who received a salary from the Qing government and whose duty was to perform rituals at the Ming tombs, and was also inducted the Chinese Plain White Banner in the Eight Banners. Later the Qianlong Emperor bestowed the title Marquis of Extended Grace posthumously on Zhu Zhuliang in 1750, and the title passed on through twelve generations of Ming descendants until the end of the Qing dynasty.
Document 2: Lady Chen (Wusu): Qian Liu died in 932, and Qian Chuanguan took over administration of the state (and changed his name to Qian Yuanguan), although for some time did not use the title of King of Wuyue but instead referred to himself by the military governor title (and, in succession, the Later Tang-bestowed titles of Prince of Wu and Prince of Yue) when reporting to Later Tang, to whom Wuyue was a vassal. (He would assume the king title only years after Lady Chen's death, in 937.) It was said that Qian Yuanguan was respectful and filially pious toward his mother. He also treated her family well, presenting them with many gifts, but never gave them offices on account of her. She died in the early "Qingtai" era (934-936) of the Later Tang emperor Li Congke and was posthumously created the Lady Dowager of Jin, with the posthumous name of "Zhaoyi" ("accomplished and benevolent").
Document 3: Wukui: Wukui's father and predecessor was Duke Huan of Qi, who was the first of the Five Hegemons, the most powerful rulers of the Spring and Autumn period. Duke Huan had at least three main wives who bore no sons, six favoured concubines, and more than ten sons. Wukui's mother was the elder Wey Ji, one of the two princesses of the State of Wey who were among Duke Huan's favoured concubines. However, the crown prince of Qi was Prince Zhao (later Duke Xiao), who was born to Zheng Ji, a princess of the State of Zheng. Four other sons of Duke Huan also contended for the throne: Prince Pan (later Duke Zhao), Prince Shangren (later Duke Yi), Prince Yuan (later Duke Hui), and Prince Yong.
Document 4: Xu Xinyue: Xu Xinyue (; 902?-August 1, 946), formally the Lady Renhui of Wuyue (吳越國仁惠夫人), was a concubine, possibly later a wife, of Qian Yuanguan (King Wenmu) (né Qian Chuanguan, name changed to Qian Yuanguan upon his succession to the throne), the second king of the Chinese state Wuyue of the Five Dynasties and Ten Kingdoms period, and the mother to his son and successor Qian Hongzuo (King Wenxian).
Document 5: Li Xun: Very little is known about Li Xun's life, including whether he was the son of his brother Li Xin's mother Princess Dowager Yin. Under his father Li Gao (Prince Wuzhao) and/or Li Xin, Li Xun successively served as the governor of Jiuquan (酒泉, roughly modern Jiuquan, Gansu) and Dunhuang Commanderies. His rule of Dunhuang was said to be benevolent and favored by the people. In 420, while trying to attack Northern Liang, Li Xin fell into a trap set by Juqu Mengxun and was killed in battle. Juqu Mengxun then quickly reached the Western Liang capital Jiuquan, and Li Xin's other brothers abandoned Jiuquan and fled to Dunhuang. Once they reached Dunhuang, they and Li Xun, then the governor of Dunhuang, abandoned Dunhuang and fled to the hills north of Dunhuang.

During his reign, his kingdom was centred on modern Zhejiang. He ascended to the throne in 932, when his father Qian Liu (King Wusu) left the state in his hands, to 941. He was the father to all three of Wuyue's subsequent kings.
Document 8: Consort Dowager Cao: Xiao Kui was not initially considered Emperor Xuan's heir, as Emperor Xuan had an older son Xiao Liao (蕭嶚), who was initially his heir apparent. However, by the time that Emperor Xuan took the throne with Western Wei support in 555, Xiao Liao had already died, and so Xiao Kui, as the next son, was created crown prince. When Emperor Xuan died in 562, Xiao Kui succeeded to the throne (as Emperor Ming). He honored Emperor Xuan's wife Empress Wang as empress dowager and honored Consort Cao as consort dowager. Consort Dowager Cao died in the fall of that year.
Document 9: Liu Chuyu: Liu Chuyu was the oldest of six children of Emperor Xiaowu's wife Empress Wang Xianyuan, although her birth date is not known. During her father's reign, her father created her the Princess Shanyin and married her to He Ji (何戢), the son of his official He Yan (何偃). After her father's death in 464, her younger brother, also by Empress Wang, Liu Ziye became emperor (as Emperor Qianfei). She became one of the people who often attended him while he visited places outside the palace. On one occasion, she told him, "While our genders are different, we are born of the same father. However, you have more than 10,000 women in your palaces, and I only have one husband, and this is unfair." In response, Emperor Qianfei selected 30 young handsome men for her, calling them her "mianshou" (面首, literally meaning "prime faces"), for them to be her lovers. (From this point on in Chinese history, "mianshou" became a term for women's male lovers, often referring to lovers of honored women.) He also promoted her to the greater title of Princess Kuaiji.
