Yetian Ancient Village is a visitor-oriented Li and Miao cultural village in Lingshui. It presents traditional houses, craft displays, dress, and performances in a curated format, so it should be approached as interpretation rather than an untouched village.
That said, it can be a useful introduction to Hainan's minority cultures if your trip is otherwise focused on beaches and resorts. Go with a critical but open eye: the staging is obvious, but the crafts, architecture, and stories still add context to the island.
