The speed for the connection of the video might be slow. The mandarin voiceover can be briefly translated as follows.
It is about a little hero named Lin Hao who is only 9 years old. When the earthquake happened, he was in the school with other 30 students. Only about 10 students escaped from the building. The little boy, who had escaped, went back to pulled out two other pupils and carried them to safety.
Now he is in Dujiangyan with his sister and we see no panic in his eyes. But till now he hasn’t found his parents yet. Wish good luck with him and wish he would find his mom and dad in the end.
