Sand-sanding is another new sport after skating, water-skiing, skiing, and grass-skiing. Players descend from the high sand dunes on the high sand dunes and experience the thrill of the cool tropical. Sand-skiing, that is, taking a skateboard to slide down from the top of the high sand. The skateboard is made of wood, bamboo, plastic, etc., sitting on the sand board, holding both hands on the slab, with your feet on the front and the body slightly forward. When the slope of the sand mountain increases and the speed of the decline accelerates, it feels like the wind is burning in both ears. In the blink of an eye, it rushes to the bottom of the mountain, and the stimulation and pleasure are experienced in the moment of surprise.
