Gu Yonglu is Gu Xiuping's grandfather, an elderly man with graying hair and sharp eyes who came downstairs early on the morning of the family trip. He joined his son Gu Weimin, daughter-in-law Ye Xianya, and granddaughter Gu Xiqi on the journey from Yanjing to Pufeng County, Qilin City. During the visit to the Wen family, he chatted warmly with Wen Yuejun while the younger generations interacted. His presence added weight and formality to the Gu family's visit, representing the older generation's approval of the engagement between Gu Xiuping and Wen Xin. The family traveled together in a jeep driven by Gu Weimin's bodyguard.
