Yuen longping ,who is an agricultural pioneer , is my favourite person.He was born in 1930.As all of you know that, he devotes all his life to his super hybrid rice,then spreads his knowledge to other coutries rapidly.This invention can help to rid the world.The reason why he is my favourite person is that he never give up in his invention and involved in this task,in spite of he need to work under pressure.The action let he become my favourite person and inspire me to  engage in my study.If I get into trouble,I also will not give up and think the method to slove the problem.
