Historical Records
Documentary Attestations
The source says that the Zheng Tongzhi, “Clan Records,” includes the surname Hai, and cites related entries from the Kaolue of Surnames, the He'nan Official Clans Gazetteer, and the Strategies of the Warring States. These are the webpage’s reports and should not be treated as verification of the original texts.

Migration and Distribution
Current Distribution
The page records the surname as distributed in Beijing, Taitung in Taiwan, and elsewhere, but gives neither population figures nor a statistical year, so no population assessment is made. It provides no more specific migration routes.

Notable People
Historical Figure
The source lists Hai Tang and describes him as a recluse during the reign of Duke Ping of Jin in the Spring and Autumn period. This identifies the person and status only and does not establish a Hai-surname family genealogy.
