Two Springs
by Li Ch'ing-chao

Spring has come to the women's quarter.
Once more the new grass is kingfisher green.
The cracked red buds of plum blossoms
Are still unopened little balls.
Blue-green clouds carve jade dragons.
The jade powder becomes fine dust.
I try to hold on to my morning dream
I have already drained and broken
The cup of Spring.
Flowers shadows lie heavy
On the garden gate.
In the orange twilight
Pale moonlight spreads
On the translucent curtain.
Three times in two years
My lord has gone away to the East.
Today he returns,
And my joy is already
Greater than the Spring.

Please help me figure out what each line is about.
