Surname Overview
Surname Attestation
The source lists “拱” (pronounced gǒng) as a current rare surname and explicitly classifies it as a Han Chinese surname; this confirms only its use as a surname within the Han Chinese naming system described by the source.

Origins
Documented Origins
The source cites the “博古图” as saying that Zhou had “拱日之彝,” and consequently states that 拱日 may have been the beginning of the surname. It also quotes the 古今姓氏书辨证 as saying that the surname existed in Linchuan, Fuzhou. These remain source-reported investigations or quotations and do not establish a single certain origin.

Research Notes
Legend and Genealogical Limits
The source also gives an account that two brothers of the Southern Song Zhao lineage changed their surname to 拱 to escape Yuan forces and fled north and south. The passage gives no primary source and says that genealogies in Hengfeng and Yanshan, Jiangxi, were not compiled until the Hongwu period of the Ming. It should therefore be treated only as a legend or family narrative reported by the source, not as proof of a shared genealogy.
