"Marquis Zhen" (). Family and relatives Guo Huai married a younger sister of the Wei general Wang Ling. In 251, Wang Ling started a rebellion in Shouchun (壽春; around present-day Shou County, Anhui) against Wei but failed and ended up being captured. He committed suicide while being escorted as a prisoner to Luoyang. The Wei imperial court ordered the arrest and execution of his family members. When the imperial censors came to arrest Guo Huai's wife (because she was Wang Ling's sister), Guo Huai's subordinates and thousands of Qiang, Di and Xiongnu tribal leaders came to ask Guo Huai to beg the imperial court to spare his wife, but he reluctantly refused. As his wife was being taken away, many people who lined the path to see her off shed tears, tried to grab her hands, and even wanted to attack the guards to save her. Guo Huai's five sons came to see their father and kowtowed until their foreheads bled while begging their father to save their mother. Guo Huai, moved by his sons' filial piety, changed his mind and ordered his subordinates to bring his wife back. Thousands of Guo Huai's men pursued the imperial censors on horseback, caught up with them, and brought back Guo Huai's wife within a few days. Guo Huai then wrote a letter to the Wei regent Sima Yi: "My five sons are willing to sacrifice their lives for their mother. If they lose their mother, I lose them too. Without my five sons, I will no longer exist. If I have violated the law by seizing back my wife from the imperial censors, I am willing to see the Emperor and take full responsibility for my actions." After reading Guo Huai's letter, Sima Yi made an exception for Guo Huai's wife and pardoned her. One of Guo Huai's sons, Guo Tong (), inherited his father's peerage and became the next Marquis of Yangqu (). He also served under the Wei government and the highest appointment he held was Inspector () of Jing Province (covering present-day Hubei and Hunan). After Guo Tong's death, his son Guo Zheng () succeeded him as the next Marquis of Yangqu. Sometime between 264 and 265, the Wei government established a new five-rank nobility system and converted Guo Huai's peerage from the Marquis of Yangqu to the Viscount of Fenyang ().
