In the classroom, a boy suddenly stood up and reminded loudly that there may be an emergency safety situation in two hours. Everyone should evacuate in an orderly manner! The classmates thought it was a joke at first and didn't pay much attention. Only I immediately handed it over and stood up because the jade ring on my hand was trembling slightly. This was the third time in the past year that it had issued a safety warning, and each time it helped me avoid unknown risks in advance. It is really important to learn to stay vigilant and pay attention to safety tips.
