Clod Sandbank With Lonely [Steve Chou]
After you've left me, my heart begins to rot.
The white tung tree is flying in the wind.
The fallen flowers follow the people to express their exquisite fellings in this season.
The wind around the river bank is blowing extremely wildly.
It continues to fiddle with women's tears.
That kind of strong love I can never give out again.
Sadness night after night.
When the lines of memory circling throught the fragmented past.
It's the dusk that occupies the heart.
There're flowers accompany the butterflies.
The lonely swallow can fly together.
In the still of the night I wander alone.
When the happy lovers send their redness to share their joy.
Closing eyes with sadness and not willing to back.
I still hate her gradually.
I'm not willing to rest even thought I fell a bit of regret.
Lonely sandbank, who should I think of?
