唐 白居易

花非花，

雾非雾。

夜半来，

天明去。

来如春梦不多时，

去似朝云无觅处。

Hua Fei Hua

by Tang Bo Ju Yi

Call it flower - 'tis not a flower;

Call it foggy mist - 'tis none such either.

It comes in the dead of the night

And takes flight the moment dawn alights;

It stays no longer than a dream in spring,

Departs like the fleeting early morning clouds -

And is seen no more.

龚景浩 英译
