Under a light blue sky, on an open grassy field, there are four squares, each packed with people some raising their hands or fists. Each square has a distinct color and expression: one with people dressed in red, one in green, another in blue, and the last in yellow. Behind them stands a thin five-story building, with every balcony also filled with cheering people raising their hands. The entire atmosphere is wrapped in an abstract sense of festivity and joy.
