In the first grade of junior high school, I ranked near the bottom during one exam and my father was called to school by the physics teacher. My father said to the teacher that I only have one daughter. Just let nature take its course. It doesn’t matter at all if she cannot do well in school. If we put too much pressure on her, she may develop psychological problems. Isn't that even worse? After returning home that day, my father didn't say a word of blaming. How important it is to grow up happily with love. It's been 24 years since my father left me. Whenever I think of him, what I recall is only warmth and happiness. He is the only person who supports me endlessly in my life. Whether he is there or not, during my ups and downs. I can weather the shocks and crisis safely. I always feel that I am omnipotent. In his time, He measured the length and breadth of the country with his steps, travelling from urban areas to rural areas. It was more for survival than for work. But he and his co-workers did build one famous hydropower station after another in China. He developed extraordinary ability in such a difficult time. I grew up at his side, and he taught me the courage to face all difficulties. Here, I would like to to pay tribute to my father.
