Question: On what date did Lady Xu Xinyue's spouse die?

full_context: Document 1: Qian Hongzun: Qian Hongzun (錢弘僔) (925－June 7, 940), formally Heir Apparent Xiaoxian (孝獻世子, "the filial and wise heir apparent"), was an heir apparent to the throne of the Chinese Five Dynasties and Ten Kingdoms Period state Wuyue during most of the reign of his father Qian Yuanguan (né Qian Chuanguan, King Wenmu), but did not inherit the throne on account of his predeceasing his father.
Document 2: 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 3: 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.
Document 4: Xiao Zhaowen: Xiao Zhaowen was born in 480, as the second son of the then-Southern Qi Price of Nan Commandery Xiao Zhangmao, the oldest son of the crown prince Xiao Ze. His mother was Xiao Zhangmao's concubine Lady Xu. Little is known about his childhood. After the death of his great-grandfather Emperor Gao in 482, his grandfather Xiao Ze became emperor (as Emperor Wu), and his father Xiao Zhangmao became Crown Prince. In 486, at age six, Xiao Zhaowen was created the Duke of Linru. In 490, he married Wang Shaoming, the daughter of the official Wang Ci (王慈), as his duchess. Early in 493, his father Xiao Zhangmao died, and his older brother Xiao Zhaoye became Crown Prince. Several months later, still in 493, Emperor Wu died as well, and Xiao Zhaoye became emperor. Xiao Zhaoye created Xiao Zhaowen the Prince of Xin'an.
Document 5: Qian Yuanguan: Qian Yuanguan (錢元瓘) (November 30, 887 – September 17, 941), born Qian Chuanguan (錢傳瓘), formally King Wenmu of Wuyue (吳越文穆王), courtesy name Mingbao (明寶), was the second king of the state of Wuyue, during the Five Dynasties and Ten Kingdoms period of China. 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 6: 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 7: 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 8: 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.
Document 9: Li Congyan: Li Congyan (李從曮) (898 – November 26, 946), né Li Jiyan (李繼曮) (name changed 926), formally the Prince of Qi (岐王), was a son and the heir of Li Maozhen, the only ruler of the Chinese Five Dynasties and Ten Kingdoms period state Qi. After Li Maozhen submitted to Later Tang and died shortly after, he continued to control the former Qi territory, as a Later Tang vassal, and subsequently served as a general for both Later Tang and its successor state Later Jin.
Document 10: Zhao Xing: Zhao Xing was the second son of King Zhao Yingqi, and his mother was a Han Chinese woman called (樛氏). In 135 BC, Zhao Yingqi was sent to the Han court by King Zhao Mo of Nanyue, to serve as Emperor Wu's guard (宿衛, "Sù wèi").

After Later Shu was destroyed by Song Dynasty, Meng Xuanzhe served as a general and official for Song.
Document 12: Wang Yuanying: Wang Yuanying (王元膺) (892 – August 13, 913), courtesy name Changmei (昌美), né Wang Zongyi (王宗懿), named Wang Yuantan (王元坦) from 910 to 912, was a crown prince of the Chinese Five Dynasties and Ten Kingdoms period state Former Shu, during most of the reign of his father, the founding emperor Wang Jian (Emperor Taizu). He was killed during an uprising he started against the powerful official Tang Daoxi and posthumously demoted to commoner rank.
Document 13: Lady Ma (Qian Yuanguan's wife): Lady Ma (馬夫人, personal name unknown) (890-November 28, 939), formally the Lady Gongmu of Wuyue (吳越國恭穆夫人), was 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.
Document 14: 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.
