Why can you see three moons in the "Moon Wind Pavilion" in Suzhou Teachers College Park?

Because the water in the pool in front of Fenglai Pavilion is clear and the moon is bright, there are no lotus flowers in the pool, reflecting the skylight and reflection, and there is a big mirror against the wall behind the pavilion, which reflects the scenery of the pool, so people say that "March" can be seen in the pavilion: one is in the sky, the other is in the water, and the other is in the mirror (the moon is reflected in the pool).
