Whenever the sun dropped and the blue sky came up, my father and I used to climb the mountain near my house. Walking together, my father and I used to have a lot of conversations through which I learned lessons from his experiences. He always told me, “You should have goals like climbing the mountain.” Without the mountain-climbing that we both enjoyed ,we couldn’t have enough time to spend together because my father was very busy. I really got a lot from mountain-climbing. It gave me time to talk with my father and to be in deep thought as well as develop my patience （耐力）.

    Once we climbed a very high mountain. It was so challenging for me because I was only ten years old. During the first few hours of climbing, I enjoyed the flowers and trees, and the birds’ singing, but as time passed, I got a pain in both of my legs. I wanted to quit climbing. In fact, I hated it at that mountain, but my father said to me, “You can always see a beautiful sky at the top of the mountain, but you can’t see it before you reach the top. Only there at the top, can you see all of the nice things, just like in life.”

    At that time, I was too young to understand his words. But later after that, I got to know hope and confidence. I found myself standing at the top of the sky, which was as clear as crystal （水晶）.
