Dear editor,

      During last year's winter holiday, I went shopping with my grandmother. We saw several beggars, some of

whom were disabled, which made me feel sad. Among them were old people, young people and even children!

When I wanted to help them, my grandmother stopped me. She told me they were not worth showing mercy

(慈悲) to because some beggars cheat (欺骗) people out of their money. Should I help them? 

                                                                                                                          Yours,

                                                                                                                          Huang Wei From Yichang

Dear Huang Wei,

      While I understand your grandmother's point of view, I think that just because some beggars have cheated

people, but this doesn't mean you should never help any beggars.

      Showing mercy and compassion (同情) to people who are not as fortunate as us is one of the kindest things

we can do.

      While some beggars may use dishonest means probably because they desperate for (极想得到) food and

feel they had no choice but to cheat people.

      It is important to be careful for your own safety. But if you want to help, you don't necessarily have to give

to beggars in the street.

     Another way you can help is by donating (捐赠) money to China charity federation. Visit its website at

www.chinaeharity.cn.net.
