In the dream, which we sang the first dedicated to all boys and girls for love songs, sky blue, grass green earth, laughter is the only universal language around the world. But when I woke up, I saw die of hunger is hunger everywhere, tell me why (why?) Does it have to do? So tell me why (why?) Is it just because I did not see, tell me why (why?) I do not understand, when we face a lot of prayer, we will only stand by and tell me why?
