last time is never found again

I think,last time is never found again
The die is cast
I can do nothing , So I often feel worried
But, someone tell me . let bygones be bygones.
The most important is tomorrow.
Without your help , I wouldn’t get rid of the puzzle for ever.
Now, look the sky,I can see phoenixes are flying
Now, listen to the natural, I can hear cranes are singing.
Now,I won’t remember the past time again .
Go ahead !
Tomorrow　must　be　better .
