If I am asked to donate something to the poor kids, I would prefer to donate food, clothes, and book. Food is the basic necessity for anyone. When the basic necessity is taken care of, others fall into the next preference such as education, shelter, medical care, etc. One can donate cash, books, food, clothes. Whenever you plan for a donation, don’t give away your used torn clothes to the underprivileged souls to get reminded of something they are missing in their life. If you wish to better the lives of poor people, change your approaches to do charity.
You can even donate a happy moment for them by organizing games, live comedy shows, magic shows for the orphanage kids
