Dear mother:
　　Maybe you would confused for my writing letter to you.Think back to the past twenty years,I suddenly find that I hardly have said to you "Thank you".I know you don't need my thanks,and you don't want any return as all mothers in the world,but today I still want to tell you:"Mum,thank you!"
　　You gave life to me.It was you who bear pain and danger gave birth to me.And from then on,you took it all you have dedicated to me.Your time,your work,your dream,it seems like they are not so important for you as before.I believe that I have been the most precious thing for you at the moment I born.Even if sometimes you get angry because me.However in a very very long time,I took it for granted that what you have done for me.
　　Time flied,I have been a university student now.The situation at the entrance exam also like yesterday,I still remember your and my father's eyes filled with concern.Twenty years,you sacrificed so much for me.I have grown up,and it's the turn for me to take care of you. Mum,thanks and I love you!
