SHOULD WE HELP STRANGERS

Recently,it's often reported that some people who help strangers are in trouble in china.That causes a wide concentration of the whole sociaty.So should we help strangers?
On the one hand, some people claim that we are supposed to help strangers who are in need. As we all know, ready to help others is a traditional value of the chinese nation. So it's taken for granted that we should keep and develope the glorious tradition.But on the other hand, some people worry that helping strangers may bring some big trouble for themselves.They're afraid of standing in their own light to do this.
As far as i'm concerned,we should help strangers.Thinking about it ,if the person who is in need is your family member or your friend,do you want others to help him (or her)? As the sing goes,roses given,fragrance in hand.Only when we help each other we can  build a harmonious sociaty toghter.
