Dear Editor,

I’m a senior high school student. It’s reported that in China many children in mountainous areas still can’t go to school as a consequence of poverty. Last week, our class held a discussion about how to help them to go to school and lead a happy childhood.

Here are our suggestions. To start with, some old textbooks and clothes can be collected and sent to those children so that they can be reused by them. In addition, it’s also of great significance to appeal to more people and social organizations to help and care for those poor children. As far as I’m concerned, we should save some of our pocket money and give it to those children in need. Above all, we should give them respect, never looking down upon them because they are poor.

We’ll really appreciate it if yocan, through the English Weekly, increase public awareness of the poor children’s living conditions and call on more people to help them.

Yours,

Li Hua
