Is “Xuanzang's family background is completely different in the novel and the official history.” true?

In Chapter 009 of "Journey to the West", it is written that Chen Guangrui achieved the top scholar title, was appointed as the governor of Jiangzhou, and was killed by river bandits. However, according to official history and "The Biography of Master Sanzang of the Great Ci'en Temple", Xuanzang's father was named Chen Hui, who served as a county official in Jiangling County, and was not a top scholar who was murdered.
