The image depicts an airport terminal signboard with several sections written in Vietnamese. The main section reads "enregistrement check-in embarquement boarding" which translates to "check-in, registration, boarding." Below this main section, there is a smaller section with the numbers "21-67," which likely indicates the flight number or gate number for the respective flight. The background of the signboard is green, and it is mounted on a building structure, possibly a terminal building. The text is in white, making it easily readable against the green background.
