Question: On what date did the father of Quan Hongzun die?

full_context: Document 1: Sun Quan: Sun Quan was born while his father Sun Jian served as the adjutant of Xiapi County. After Sun Jian's death in the early 190s, he and his family lived at various cities on the lower Yangtze River, until Sun Ce carved out a warlord regime in the Jiangdong region, based on his own followers and a number of local clan allegiances. When Sun Ce was assassinated by the retainers of Xu Gong in 200, the 18-year-old Sun Quan inherited the lands southeast of the Yangtze River from his brother. His administration proved to be relatively stable in those early years as Sun Jian and Sun Ce's most senior officers, such as Zhou Yu, Zhang Zhao, Zhang Hong, and Cheng Pu supported the succession. Thus throughout the 200s, Sun Quan, under the tutelage of his able advisers, continued to build up his strength along the Yangtze River. In early 207, his forces finally won complete victory over Huang Zu, a military leader under Liu Biao, who dominated the middle Yangtze.Huang Zu was killed in battle.

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.

(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.

Document 9: Yuan dynasty: Following the conquest of Dali in 1253, the former ruling Duan dynasty were appointed as governors-general, recognized as imperial officials by the Yuan, Ming, and Qing-era governments, principally in the province of Yunnan. Succession for the Yuan dynasty, however, was an intractable problem, later causing much strife and internal struggle. This emerged as early as the end of Kublai's reign. Kublai originally named his eldest son, Zhenjin, as the Crown Prince, but he died before Kublai in 1285. Thus, Zhenjin's third son, with the support of his mother Kökejin and the minister Bayan, succeeded the throne and ruled as Temür Khan, or Emperor Chengzong, from 1294 to 1307. Temür Khan decided to maintain and continue much of the work begun by his grandfather. He also made peace with the western Mongol khanates as well as neighboring countries such as Vietnam, which recognized his nominal suzerainty and paid tributes for a few decades. However, the corruption in the Yuan dynasty began during the reign of Temür Khan.
