"There! Little Yang-Yang wants to go there." the young boy led the group on a river where a gleaming light existed. As they walked closer, they saw the light of a full moon slowly appeared in the running water. The current was running smoothly and this image of the moon looked like it was dancing in the water.
At first glance, anyone could think that the moon was just a reflection. But strangely, there was no moon above the sky that could possible reflect on the river. It was as if the moon only existed inside the water.
"Why is there a moon inside the river but not above the sky?" Jang Ji rubbed his chin and deeply pondered at the scenery. He stared at where the direction where the river flowed. A few feet away from them, he saw three huge stones which would look like it was arranged to be the bridge when crossing the river.
