原文歌词
EN暂时没有翻译，当前显示原文歌词。
When you're smiling, keep on smiling,
The whole wide world will smile with you;
And when you're laughing (ha, ha, ha, ha!), keep on laughing (ha, ha),
You'll find the sun will come shining through!
But when you're crying (boo-hoo), you bring on the rain;
Stop your sighing and be happy again.
When you're smiling, keep on smiling,
