What is behind this poem?

Peach is full of rain, willow green is more smoky. The flowers have fallen, and the children haven't cleaned them, but the guests in Ti Ying Mountain are still sleeping.

Ten years of hard work, grinding out a sword, the blade of the cold light flashing, but did not try its edge. Today, I will show you who is unfair.
