As Gu Shaocheng thought to himself, he jumped into the water first, reached out his arm and gently ushered her, "Come down."
She didn't dare to jump in, so she walked to the edge of the pool and, holding onto the side, slowly lowered herself into the water.
So Gu Shaocheng began to hold onto her body, patiently teaching her, "The first step in learning to swim is learning to hold your breath. Each time you're about to run out of air, slowly exhale. Remember: you must start slow! And keep trying different exhalation speeds. Did you get that...?"
Gu Shaocheng rarely has this much patience. He stood in the water, first explaining the theory to her, then demonstrating to her how to hold her breath.
Chenxing listened intently and followed diligently, but she choked a few times at the beginning.
