No mater how far a migratory bird may fly, it always misses the south.
The heaven of a traveller who has been to the ends of the earth, is still home.
My next stop, I can't be sure yet whether it'll be cold or warm.
When dawn breaks, I will leave again.

If I come back, will there be someone waiting?
If I am lonely, is there anyone who understands?
I imagine us meeting again, but I fear I have no courage
to wish to be in your arms.

There's an echo from the tunnel of past times,
won't you listen to that?
That is what we had back then,
a happy pinky promise.

Some people stay in our hearts, unforgotten.
Some things, some dreams, are yet to have a definite answer.
Some words, the harder it is to say,
the lovelier they will sound.
Let us come close, I wish to tell you quietly
how much I love you.

This heart of mine is still there, it never left.
I went all around the world, but what is most precious is you.
Do you still remember your favourite song?  Let me sing it for you
and tell you quietly how much I love you.

The original song in Mandarin:  悄悄告诉你 / 范玮琪  (link)
*I did not translate word for word, I just wrote what I think the song wanted to say in simple English.
