My first teacher was my mother. I have mentioned that it was my mother who made me know what love is. When I was young, she was the center of my world. She gave a perfect expression to love and let me realize the warmness between humans. She also made me know the happiness of loving and being loved. She always explained various things to me in a mild tone and taught me to love all people, no matter they are poor or rich. Furthermore, she taught me to help those people who were in hardship and needed support and she taught me give sympathies to the servants who are in bad condition. She told me that we shouldn't put myself in a more superior position than them and shouldn't beat and scold them.

My mother also experiences some adverse situation. For example, she had even been a daughter-in-law in a big family. We can imagine the misery she suffered. However, my mother didn't weep a tear in front of me, or even didn't said a sorrowful word to me. She only showed me a gentle and smiling face.
绝对是我自己翻译的哦，呵呵。
