There is one person visible in the image. They are wearing a blue shirt and appear to be standing near a body of water, possibly a river or lake. The person is holding a sign that reads "Ngân ngập nước >= 40 cm" which translates to "Water level >= 40 cm." The sign is attached to a pole, and there is another pole in the background with a banner hanging from it. The overall scene suggests a flood warning or a water level monitoring sign.
