One of these guys notices a small girl on the fourth floor about to fall. The rest come to help. One broke his arm and another hurt his neck. The girl is unharmed.
This video reminds me of the ancient Chinese philosopher Mencius who said that people are fundamentally good. One way he showed that was with the thought experiment that there are very few of us who would not rush to save a child about to fall into a well. As you watch this video, I bet you feel good seeing the girl saved, which shows the same thing in another way.
