There is only one life, and there is only one earth!
Everyone abides by the safety rules and always lives a happy life.
Life first, safety responsibility day.
Health is the source of happiness and safety is the basis of production.
Safety is the greatest saving, and accidents are the greatest waste.
The wife blows the safety pillow wind, and the husband remembers the rules.
Hand in hand, mouth in mouth, I won't go if you don't come. "Three violations" watch me walk around.
