A Mid-Autumn Festival poster set in a school courtyard at night, with a large, glowing full moon hanging over the campus. In the foreground, a group of students and teachers are sitting together, enjoying mooncakes and sharing stories under the soft glow of lanterns. The campus buildings, subtly lit by the moon, showcase the school’s architecture in the background. A gentle breeze sways the lanterns hanging on trees, and the night sky is deep blue, filled with stars. The text reads "Campus Reunion, Together We Learn and Grow," written in a brushstroke style. The ISA logo is softly integrated into the moon’s design, and a few lines about the school’s educational values are subtly placed in the corner, connecting the festive atmosphere with the school’s mission.
