happiness is nothing but a kind of feeling deeply in your heart ,which makes you lucky ,happy ,and moved. a hug from your best friend when you are in trouble ,a cup of tea from your love when you are thirst ,and also some encouraging word from your parents when you failed will make you happy. 幸福什么都不是，它是发自内心的使你快乐、高兴、感动的情感，它是你在困境中朋友的一个拥抱，它是你饥渴时的爱人端来的一杯清茶，更是你失败时父母鼓励的话语。
safe and happy中英两种语言互译，绝不是一对一的萝卜对坑坑。文章不是这样，词汇也不是。“平安”二字，说来简单，但同样不能以一词来取代全部，否则便是以偏概全。不同语言环境，措词不一。如：祝你一路平安（Wish you a good journey）。本句平安二字从何体现？好像是good，但你决不能说good便是平安。一切平安无事（All is well），似乎平安又变成了well。基督教中的赞美诗《平安夜》（Silent Night），silent译成平安。还有大量的例子说明这一点。所以不同语境翻译不一样
