The unpowered boat uses the paddles to master the direction, and then flows down the current stream in a rushing and rushing time. In the moment of fighting against nature, this is the drifting, a brave movement. A meandering river that stretches over the hard hinterland of the canyon. Take a rubber boat down the river, the sky is high and the water is long, the sun is shining, surrounded by green hills, drifting in the meantime, oncoming is an expectation - look forward to stimulation! Looking forward to thrill! Looking forward to fighting with nature! I look forward to the ease of "surprise!" In the busy urban life, people are always looking for such an excitement, a unique feeling that is different from ordinary life. It is such a feeling that the urban people dump it and make it a part of life.
