I came across with an old man in rags the other day, he was begging for a living. To be frank, I didn’t know how I ought to give him some money. On the one hand, I am not born in a rich family. On the other hand, old as the man was, he was in good health. In most people’s opinion, he should be able to earn her living instead of be a beggar. All of us ought to help those who is really in need. However, what matters is that all the people should try to depend in themselves first. Therefore our society can be much harmonious, which is we all look forward to.
