On one hand, there are people who live their life richly. They are enjoying not only the joy of essential but also the luxurious living. On the other hand, there are people who not cannot even afford the basic requirements of living. They do not have shelters to live, food to eat, and clothes to wear. They have inadequate nutrition, higher risk of diseases and lack access to healthcare and basic essential for living. They have to fight each day for life. Helping the poor is very essential. There are many ways to help the poor but I think the best way is providing education.
Providing knowledge can help the poor to stand on their feet. Education is the beginning of getting our from hardships of life. Giving free education to the poor help them to grow as individuals and help them lead an independent life. Education can help them to get a job, be employed build career and acheive success capabillity of handling problems and lead a successful life. The poor can become better self - sufficient and better human being through the power of education. Through education, we can help the poor to develope their skills so that they can take over efforts to revitalixe their life rather than always depending on the outsiders to do so for them.

Chúc cậu học tốt!
