塞翁失马：坏事一定能变好事吗？

An old man once lived near the border. 从前有位老爷爷，住在边境边上。 One day his horse ran away. 有一天，他家的马跑丢了。 His neighbors said it was bad luck. 邻居们都说，这可真倒霉。 Days later, the horse came back with more horses. 过了几天，马带回了一大群马。 Then his son fell off a horse and hurt his leg. 结果他儿子骑马摔了，腿受了伤。 Good and bad can switch places anytime. 好事坏事，说不准哪天就换了位置。 That is the story of "sai weng shi ma". 这就是“塞翁失马”的故事呀。
