Should one expect a rewarding when doing a good deed?

Different people have different view about whether or not one should expect a rewarding when doing a good deed.Some argue that people should be encouraged by a reward for a good deed,because they may believe the saying "no pains,no gains". While others have different viewpoint.They regard Lei Feng,a hero in China,who always helps others without ever asking for any reward.They think they can get happiness through what they have done,the peace in their heart is the best return.Helping others is an indispensable part of their virtues,we should offer help without payment.They also think that doing good deeds is good for both others and theirs. As for me,it is not important whether we have got rewards,but we have tried our best to help those in trouble.If all of us can help each other,our society will be more civilized and harmonious. And what do you think about this?
