我曾经听到过一个故事。有一只可爱的小狗问它的妈妈:“妈妈,妈妈,幸福在哪里呀?”妈妈笑着对它说:“幸福呀,它在你的尾巴上呢!”“噢,尾巴上!”于是小狗就急忙去抓它的尾巴,可是不知为什么头都抓晕了,却还是抓不到尾巴。这可急坏了小狗,赶忙去问妈妈:“妈妈!妈妈!我怎么头都抓晕了,还是没见到幸福啊?” I once heard a story. A cute puppy asked its mother: “Mom, mother, where is happiness?” Mom smiled and said to him, “Happiness, it’s on your tail!” “Oh, on the tail!” The puppies rushed to grasp its tail, but somehow the head was caught dizzy, but still did not catch the tail. This could have ruined the puppy and hurried to ask her mother, “Mom! Mom! I’ve caught my head and I still don’t see happiness.”
