In the Wenchuan earthquake in 2008, there were still three students in a school who couldn't keep up with the team. Finally, a teacher hid them under the platform and protected the three students with his huge body. There was a big stone on his shoulder, but he gritted his teeth and didn't let it hurt his classmates. He used his last strength to protect three students. But the teacher seemed to make things difficult for him, so he left this world. At that moment, I shed tears. I shed tears for this teacher's indomitable spirit of self-sacrifice. I found a smile on my lips when the teacher left. I think this is the most beautiful smile in the world. I think it is worthwhile for him to leave because he saved the lives of three students. I firmly believe that teachers are in the spirit of heaven, and it must be very gratifying to see students living happily.

The teacher's smile is the most beautiful, and his quality is the noblest!
