There are three people visible in the image. They appear to be engaged in some activity related to recycling or waste management. The person on the left is wearing a green shirt and appears to be standing close to a green truck with a sign that reads "回收車投縣公所" (recycling vehicle county government). The person in the middle is also wearing a green shirt and seems to be interacting with the truck. The person on the right is partially visible and is also wearing a green shirt. They are all focused on their task, possibly loading or unloading items from the truck.
