Notice: Spring Festival fire safety
The Spring Festival is coming. Fires are easy to happen, so we must pay attention to fire safety. Fires usually start at night and they often break out in homes, corridors（走廊）or kitchens.
Common reasons:
▶ Set off fireworks too close to buildings or near dry grass.
▶ Forget to turn off kitchen stoves after cooking.

✓ Use stairs to get out of the building—NEVER the lift!
