Peeling The Pearls Of Wisdom

On this wall of literary world,
I will spread the spontaneous words
From a short piece to a long piece
Sometimes using short key
Unlocking the padlocks of the world
With words, I often break deadlocks
Even with a loose code
I still hit the bedrocks

On this mat, I will spread the literary world
With wise words to guide the wise guys
For the foes and fools, I don't want to waste fund
Except sometimes when I want to make fun
An advice to the wise probes them wiser
But to the fool, it only hits the canary island.
