Remembrance of things past My hometown lies in a beautiful river valley; the river doesn’t have a name. When I was a little boy, I used to swim in the river. Especially in summer day， I almost spent all day on the river: Swimming, fishing or digging small-scale canal. The most interesting thing must have been digging small-scale canal. It is a team work rather than a personal work. So, when digging small-scale canal, there were many friends digging together with me. We moved the stones, grubbed the sands so that the water could go wherever we wanted it to go. Sometimes we floated small paper boat in the small-scale canal. Those boats were folded by waste paper and had various appearances.
