Two wooden boats drift towards each other beneath Hạ Long Bay's limestone towers. A woman in a purple tunic sings a melody across the water; a man on the other boat answers with a teasing verse. This is hát giao duyên — romantic call-and-response folk singing — and after a pause for restructuring, it has officially resumed at the Cửa Vạn floating village in Quảng Ninh Province as of March.
What sets this art form apart is that it never came from royal courts or village halls. It was born entirely at sea, used by Hạ Long's fishing communities to chat between boats, pass the long hours on the water, and express love, luck and hopes for a safe voyage. A session follows an old courtship arc: greetings and playful questions that can run until dawn, then a battle of wits covering astronomy, geography and local folklore, then the exchange of tokens — a conical hat or a scarf — before bittersweet farewell songs close the night.
Quảng Ninh first staged performances at the Cửa Vạn Floating Cultural Centre in 2017, and the March revival is part of a wider push to keep the province's intangible heritage genuinely alive rather than preserved behind glass. The revival also ties into Vietnam's national cultural policy (Resolution 80-NQ/TW), which encourages turning living traditions into sustainable, high-value tourism experiences practised by their original communities.
Purists will appreciate that nothing has been modernised away. There are no instruments, no stage set — the open bay is the theatre, and its waters act as a natural echo chamber. The lyrics still weave in local place names, old village titles and coastal idioms unique to the Quảng Ninh shoreline, keeping the art anchored to the place that created it.
For travellers, this is a genuine alternative to the standard boat-cruise-and-photo routine. Hạ Long Bay's karsts are world-famous, but the return of hát giao duyên adds a sound to the scenery: at sunset, with floating homes around you and farewell songs lingering over the water, the bay becomes an experience you hear as much as see. If you're drawn to slow, immersive cultural travel, time your visit to catch a performance at Cửa Vạn — one of the bay's most celebrated floating villages — and you'll be watching a tradition that fishermen have sung into the air here for generations, now shared with the world again.
