Not much is recorded about Taigong historically. He was born and likely lived his early life in present-day Feng County, Jiangsu. His personal name is not known. Some historical sources says his name is Liu Zhijia (Chinese:劉執嘉), although this name is likely chosen after Liu Bang became Emperor. He likely came from a humble, rural background.
After Taigong's son Liu Bang became emperor, Liu Bang continued to visit his father once a week. However, upon hearing from an advisor that it was no longer appropriate for Taigong to "receive" his son, as Taigong was technically one of his subjects, Taigong began to greet his son in deprecatory fashion, honoring the latter's status as emperor. Upon learning the reason behind his father's actions, Liu Bang honored Taigong with the title Taishang Huang on 4 July 201 BCE,[3] a year after Liu Bang declared himself emperor in February 202 BCE. The title nominally elevated Liu's status in court protocol as to remain consistent with Confucian norms of filial piety.
Taigong died at a palace in the city of Yueyanginc.June 197 BC. On 9 August 197 BC,[4] he was entombed in present-day Lintong District, Xi'an.
