Why do wild horses gallop? With their heads raised and tails waving, their muscles throbbing, their chests racing, they gallop endlessly. In the summer storm, towards the lightning, the wild horses gallop endlessly, but one day the horses stop. A mystery of nature.(wonder) Perhaps feeling it, the wild horse closes its eyes, motionless like a bronze statue. Why does it keep galloping? It stretches its neck, swings its tail, and the throbbing of life in its heart keeps galloping endlessly. Under the summer sun, the wild horse keeps galloping endlessly, heading for the truth.
