It seems like a silly question, anyone in sane would give a hand to the elderly who fell. But in China, this question is becoming tricky. Many news report that there are some old people not just fell, they do it on purpose. Usually, they walk on a crowdy street, and pretend to faint or just lay down on the ground, intend to accuse the one who comes to help as a perpetrator and blackmail him/her for the treatment fee. Many people h**e fell for that and had to pay as there is no witness to prove their innocence. As for these negative news, people is afraid to help those old people in need, that makes some of them who are in real trouble could not get help in time.
I once asked one of my friends: “Why the old people turn bad? If you see one in the street, would you help?” He said: “It is not the old people turn bad, it is the bad people turn old. I will video him/her to make a statement first, then decide if I would help.”
