Should one expect a reward when doing a good deed
Lei Feng,a communist soldier,who "devoted his limited life to the limitless cause of serving the people",has long been set as an outstanding example to encourage us to spare no efforts to help those in need,whereas,with the passage of time,people voice different opinions towards doing good deeds.
Some insists "A good turn deserves another",as the old saying goes,which indicates that a good deed ought to bring about a reward,the motivation or the stimulus for the favor.Meanwhile,others believe good deeds belong to voluntary work,purely out of willingness,which has nothing to do with expectation for rewards.
As to me,good deeds are supposed to result from spontaneous reaction confronted with certain circumstances,ranging from giving up one seat to a silver-haired passenger aboard the bus,donating blood to the designated organization by Red Cross to traveling to the remote and poverty-stricken areas to serve as a volunteer for a whole year.In short,rewards are by no means the trigger or purpose for intention of conducting good deeds,no matter how trivial or stunning they are.
