Play around,
Dangerous thoughts
; Life is precious, so cherish it.
Cross the aisle, not crowded; Do exercises and pay special attention.
Don't chase, don't make trouble, don't worry; Drive slowly on the right and be safe.
Students, don't forget; Be disciplined when going up and down the stairs.
Don't squeeze, don't.
holding hands
Don't carry, don't slide, and always keep your heart safe.
