    When I was young, I was terribly poor in the Chinese. Be afraid of expressing myself was one of the reasons why I rarely did well in school. Once I failed in a mid-term exam. When I got the papers, I realized things could have been better if I listened to the teacher much more attentive. So I turned to my teacher for helps and he told me, “Where there is a will, there is a way. If you are devoted to learn Chinese, you'll make it.” I couldn't agree much. From then on, I began to work harder. Out of my expect, I made great progress soon. Today, Chinese is which my strength lies. And I'm grateful for my Chinese teacher.
