1. The stream water is very clear and there are many fish. Children like to catch fish very much. 2. It's very tired to climb mountains with flat rocks, and it's fun to go through. 3. You can climb the mountain, but because the children want to catch fish, they did not climb the mountain. 4. Walking up and down the mountain without climbing, there are 4 hours (catching fish and resting for about 1 hour). Enjoy the air and joy of the upbringing bar. 5. I walked along the trail and saw many grasshoppers, horse snakes, snakes, swallows, butterflies and flying insects.
