Hairui Tomb (海瑞墓) is the burial site of Hainan's most celebrated official — a Ming dynasty administrator whose reputation for honesty was so extreme it became legendary across China. Hairui served in various posts across the empire, consistently refusing bribes, cutting through bureaucratic corruption, and siding with ordinary people against powerful interests, at enormous personal cost.
The tomb complex includes a small museum explaining his life and career in the context of late Ming dynasty politics. The site has particular resonance for Chinese visitors: Hairui was rehabilitated after the Cultural Revolution (having been used as a propaganda target during it), and he remains a touchstone figure in Chinese public life whenever corruption becomes a political issue.
