Guo Zixing's family owns property, and he usually makes friends with many brave people. There was chaos at the end of Yuan Dynasty. He was in Zheng Zhi 12 (1352), and he assembled thousands of people to buy Haozhou, that is, at this time he appointed Zhu Yuanzhang as a centurion, which was reused because of his meritorious military service.
Although Guo Zixing repelled the Yuan Army, he fought with Sun Deya, Zhao Junyong and others in the camp and was almost assassinated. Later, he joined Zhu Yuanzhang's army. With his support, he parted ways with Peng, Zhao and Sun, moved to Chuzhou, served as the commander of Zhu Yuanzhang's army, and married his adopted daughter to Zhu Yuanzhang. He died in 1355, and his influence was probably inherited by Zhu Yuanzhang, who made him King of Chu Yang in 1370.
Guo Zixing is fierce and aggressive, honest and frank, but irritable and suspicious. When things are urgent, I always listen to Zhu Yuanzhang's advice and trust him as I trust my right-hand man. But after the matter was solved, he immediately listened to rumors and alienated Zhu Yuanzhang. Guo Zixing also called all capable people around Zhu Yuanzhang and slowly deprived him of the relieving. Therefore, Zhu Yuanzhang was more cautious when working for Guo Zixing. Ma Huanghou always gives anything from a soldier to Guo Zixing's wife.
When Guo Zixing arrived in Chuyang, he wanted to be king on the spot. Zhu Yuanzhang dissuaded him: "Chu Yang is surrounded by mountains, and ships and caravans can't get through. It is not a place where one can be safe day and night. " Guo Zixing this just forget about it. When he occupied Hezhou, Guo Zixing ordered Zhu Yuanzhang to lead his troops to be stationed in Hezhou. Because of the famine, Sun Deya went to eat in the state and asked to station troops in the city. Zhu Yuanzhang accepted him. Someone slandered Guo Zixing and falsely accused Zhu Yuanzhang. Guo Zixing rushed to Hezhou overnight, and Zhu Yuanzhang came to visit. Guo Zixing was very angry. He didn't talk to Zhu Yuanzhang.
Zhu Yuanzhang said, "Sun Deya once imprisoned you, so we should guard against him." Guo Zixing didn't speak, but in his heart he thought he was right. When Sun Deya heard that Guo Zixing had arrived in Hezhou, he wanted to lead his troops to escape. The former battalion has set out, and Sun Deya stayed in the rear army for inspection. At this time, his army fought against Guo Zixing's army, and many people died. Guo Zixing captured Sun Deya and Zhu Yuanzhang was also captured by Sun Deya's army.
Guo Zixing was surprised when he learned about it. He immediately sent Xu Da to replace Zhu Yuanzhang and put Sun Deya back. Sun Deya's men released Zhu Yuanzhang, and Xu Da escaped. Guo Zixing hated Sun Deya's guts and wanted to kill him quickly, but because of Zhu Yuanzhang, he was reluctantly released, so he was always unhappy. Soon, he died of illness and was buried in Chuyang.
