The image shows a banner with text in Vietnamese. The banner is displayed outdoors, possibly at an event or protest. The text on the banner reads: "Cảnh báo nguy hiểm khu vực có nguy cơ sạt lở." This translates to "Dangerous area, risk of siltation." The banner appears to be part of a larger gathering or demonstration, as suggested by the presence of other banners and signs in the background.
