Once upon a time, a long, long time ago, men and women lived happily together and worked in harmony.

Once upon a time, a long, long while ago, the Sun, the Wind, and the Moon were three sisters, and their mother was a pale, lovely Star that shone, far away, in the dark evening sky.

从前，在很久很久以前，太阳、风和月亮是三姐妹，她们的母亲是黑暗夜空中遥远地闪烁著的一颗很淡却又很美丽的星星。

Once upon a time, not long ago.
