Out of sight does not mean nobody is there
Xiaohe is heading to the playground at break time. A wall hides the next hallway. If he runs around the corner before noticing an approaching child, both children may have less time and room to respond.
Slow down before the corner, watch the route and give others room to pass. Do not dart your head out or call out and then rush ahead. Save chasing games for a suitable, permitted play area.
We can see both children in the cutaway drawing so that we can understand the blocked view. Xiaohe cannot see through the wall. The line shows a line of sight on a floor plan, while the figures stand upright so we can recognize them. It is not a perspective ray drawn at the children’s actual eye height. Follow the child in the blue-green shirt throughout the story.
How would you pass the next corner?
After the story, choose an action. Slowing down lets Xiaohe notice the other child, leave room and continue. Choosing to rush pauses the picture before the dangerous action and gives you a chance to reconsider.
With an adult, discuss other places where views can be blocked, such as classroom doors and restroom exits. Find them on a simple map. Do not test them by running or suddenly jumping out.
Children can still enjoy normal break-time activity in suitable areas where school rules allow it.
For parents and teachers
Why explain the blocked view first?
A child may confuse “I cannot see anyone” with “nobody is there.” Revealing the hidden approach connects the rule to something observable. Do not blame an affected child for an accident. Adults and schools also share responsibility for supervision, the environment and safe movement arrangements.
What are the limits of the picture?
The same geometry determines character positions and whether the line of sight crosses the wall. Paths and timing are authored teaching examples. They do not predict real walking speeds, reaction times, collision probabilities or injuries. Slowing down is not an absolute safety guarantee; follow local conditions and school rules.
China’s National Fire and Rescue Administration school safety reminder advises against running and chasing in classrooms, hallways, stair entrances and hallway corners.
