The wind of late spring carries the sweet fragrance of magnolia flowers, blows through the streets paved with bluestones, and gently hits the red lacquer door of the "Minghui School". Xie Yi was bending down to water the orchids on the windowsill. As soon as his fingertips touched the edge of the pottery pot, he was tickled by a falling magnolia petal. He straightened up and looked at the half-grown children chasing butterflies in the courtyard. The water droplets on his sleeves slid down his blue cloth clothes, leaving small wet marks on the ground.
