The origin of the Guo family in Ningbo, Zhejiang Province can be traced back to the Han Dynasty. The book Yuan He Shi Bian records: "Guo, Zhou Youguo, was destroyed by Jin, and the city was also." As a surname, Guo first appeared in Xia, Shang and Zhou dynasties, and later, with the passage of time, Guo's descendants gradually spread all over the country.

The Guo family in Ningbo is said to have migrated from Chengyang (now Shandong). In the early Ming Dynasty, Guo Zixing moved from Chengyang to Yuehu Lake in Ningbo during the Hongwu period (1368- 1398), and his descendants became local aristocrats.
