Bole wrote all his horse skills in a book called "To Ma Jing" and drew all kinds of horses. Bole's son is stupid, but he wants to be as good as his father. Bole's son remembered Xiang and thought that he also had the ability to recognize horses. One day, Bole's son saw a toad on the side of the road. He remembers the book saying that a good horse is a horse with a bulging forehead, bright eyes and four big hooves. "This guy has a bulging forehead and big bright eyes. Isn't it a swift horse? " He thought. He was so happy that he took toad home and said to Bole, "Look, I found a good horse!" " "Bole was in distress situation and had to say," Matthew you caught loves to jump. It is not easy to ride! "
