As is often reported, an old man is lying on the ground, while the passers-by are all hesitating over whether to offer help or not, fearing that it may incur unwanted trouble, which has aroused great concern on this problem and heated debate on whether we should help those old people falling on the street.

In my view, there are two reasons that may account for this phenomenon: on one hand, it is often believed that some people with evil intentions adopt this method to blackmail those friendly and helpful people. So people now are more risk-conscious and wary of such traps and deceits. On the other hand, due to the increasing pressures from modern life and the well-accepted concept that time is money, people tend to care more about themselves than others, not to mention helping a stranger. When egoism gains the upper hand, many people find it growingly hard to help others.

Helping others has always been a virtue in traditional Chinese culture. But what’ s a pity nowadays that people dare not show their helping hands to those in need. Therefore, we should stick to and carry on this fine tradition. Of course, we should also look out for potential hazards so as not to be deceived. In order to protect the profits of those warm-hearted people, the government should take measures to increase education on morality and conscience. Besides, some legal principles can be put forward if necessary since only by getting rid of the worry can people help them actively. To sum up, helping others is to help ourselves. We should be generous to do a favor to those in need thus making our society more harmonious.
