After his coronation, Emperor Wu appointed Wang Xiang as Grand Protector () and allowed him to keep his peerage as the Duke of Suiling. By then, Wang Xiang, He Zeng (), Zheng Chong () and some former Wei officials were already in their old age, so it was no longer convenient for them to regularly attend imperial court sessions. Emperor Wu thus sent Ren Kai (), then a Palace Attendant (), to visit them and seek their advice on policy matters. Wang Xiang, then already in his 80s, sought permission on a number of occasions from Emperor Wu to retire, but the emperor refused. Hou Shiguang (), a Palace Assistant Imperial Clerk (), once asked Emperor Wu to dismiss Wang Xiang because Wang Xiang had been absent from imperial court sessions for a long time due to poor health. However, as Emperor Wu respected and favoured Wang Xiang, he ordered the Imperial Censorate (; in charge of keeping track of officials' performance in office) to make an exception for Wang Xiang. He also allowed Wang Xiang to remain in office and continue drawing his salary, even though Wang Xiang spent most of his time at home. Wang Xiang died in April 268 at the age of 85 (by East Asian age reckoning) and was awarded the posthumous title "Duke Yuan" (). Hence, he was formally referred to as "Duke Yuan of Suiling". Family Wang Xiang's half-brother, Wang Lan (), served as a Household Counsellor () under the Jin dynasty. He was also a fourth-generation ancestor of the famous calligrapher Wang Xizhi. Some known descendants of Wang Xiang are as follows: Wang Zhao (), Wang Xiang's first son born to a concubine. He served as a Cavalry Commandant (), Official Who Concurrently Serves in the Palace (), and the Administrator of Shiping () under the Jin dynasty. Wang Jun (), Wang Zhao's son, served as an assistant to the crown prince, later enfeoffed as the Marquis of Yongshi (). Wang Xia (), Wang Jun's son, served as the Administrator of Yulin (). Wang Xia (), Wang Xiang's first son born to his wife, died early. Wang Fu (), Wang Xiang's second son born to his wife, inherited his father's peerage as the Duke of Suiling. He served as the Administrator of Shangluo (). Wang Gen (), Wang Fu's son, inherited his father's peerage as the Duke of Suiling. Wang Lie (),
