实践证明，加强社会治安综合治理是建立和保持良好的社会治安秩序、维护社会政治稳定的基本

Help or Not

Dear editor,

During last year's winter holiday, I went shopping with my grandmother. We saw several beggars. Some of them 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 to because some beggars cheated people out of their money. Should I help them?

Yours,

Mary from Guangzhou

Dear Mary,

While I understand your grandmother’s point of view, I think that just because some beggars have cheated people, this doesn’t mean you should never help any beggars.

Showing mercy 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 to get money, most beggars will not. Even those who use dishonest means are probably hungry for food and feel they have 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 it to beggars in the street.

Another way you can help is by donating money to the China Charity Federation. Visit its website at: www. china charity. cn.net.
