This is story behind the well-known saying: 赛翁失马,焉知非福也
It was lifted from a book of parables.
The old man living on the plains lost a horse. His neighbours came to comfort him about his loss. The old man said: who knows, it may be a blessing. Sure enough, the ‘lost’ horse came home, with another horse – a thoroughbred. His neighbours came to congratulate him. The old man said: for all you know, it may be a misfortune. One day, the old man’s only son rode on the newly acquired horse, fell from it and broke his leg. Again, his neighbours came to comfort him. The old man said: maybe, this is a blessing. There was a war and the army came to conscript young men for it. The old man’s son was let off because of his broken leg. And this saved his life.
Life is a series of ups and downs. One never knows until the end. Whether one has gained or lost. But this also depends on how you view your ‘achievements’. The wise old man knows. Fret not, when one thing is lost – for you may gain another. Rejoice not, when one thing is gained – for everything has a price. But I guess the point is – always look on the bright side of life.
