Once upon a time, there lived an old man who owned a wonderful horse on the frontier of China. One day, the horse jumped a fence and ran away. His neighbors came to comfort him. But he looked so peaceful and serene. He said, "Don't judge, who can say this may be good or bad?"
A few months later, the horse returned home and came back along with a group of horses. His neighbors came around again. The old man was congratulated by them, but he said: "Don't judge, who can say this may be good or bad?"
A few days later, his son went out riding on the horse, fell down from the new horse and had his leg broken. Everyone in the village came to comfort him again. However, the old man said, "Don't judge, who can say this may be good or bad?"
Some days later, the country where the old man lived got engaged in the war against its neighborhood, so all the young men in the village were drafted to fight in the war. Most draftees were killed in the battle. However, his son was not conscripted to fight in the war because he was a cripple. Everyone in the village said to the old man, "Your son is so lucky." However, the old man said, "Don't judge, who can say this may be good or bad?"
