I just want to share a story to you.Maybe you purse something for many years and you get nothing.You should give it up.This song is my all experience. That is my true story.I see a girl in crowds.I dream her in my dream .She is my favorite.But I donot close to her. But I cannot forget her at all.So some years later.I use my all ways to find her.I find her classmates on the Internet. I get her contact information from her classmates and I use many ways to contact her.I persude her but it is failed.Now I do similar things like this. I write many letter to Andy lau's music company and I wish he can sing this song called knowledge water.At last,if I am failed,but it doesnot matter.I just need a cup of forgiven love water to forget this thing and a cup of knowledge water to use knowledge to face everything and have a good life.This is the theme of this song.Life is not dreaming,sometimes life cheats you.You should be calm and tenacious all the time,use knowledge to life.That is my all.I wirte my all. I donot do this thing anymore.This is also everybody's all,you use the whole life and try all your strength to drink a cup of knowledge water,use knowledge and right ways to be rich and happy.Because this song can take into everybody's heart so it must be popular around the world.If Andy lau canot sing this song called knowledge water,I donot care the result at all.I always be happy and brave to life.All the success and failure,make it disappear with the wind ,the miss cannot be got again.Take it easy.Ijust wait the result and concentrate on preparing exams for public institution.Wish the world is wonderful all the time and this song encourages everybody around the world.
