After breakfast.
The students from Class Four had cultural knowledge classes all morning and then, after a lunch break, were called to the school's swimming pool in the afternoon.
Standing at the edge of the pool, they gazed at the crystal-clear water, swallowing hard as a flicker of fear crossed their faces, only to be quickly concealed.
