Seeing the students of the literary club puzzled,
Teacher Liu smiled and explained to everyone: "Do you still remember the ruthless couplets I once mentioned to you?"
"Yeah!"
Everyone nodded in response.
Ruthless couplets.
This is a form created by a noted master in the early years, but very few use it, as it's a rather obscure form within obscurity!
"That's good. This is actually a ruthless couplet."
Teacher Liu Chen nodded in satisfaction and began to explain in detail:
"The tree has been felled halfway, no need to swing the axe further, indeed entirely unrelated."
"Tree corresponds with fruit, both being nouns; a dot corresponds with thousand fathoms, both being units of measure, where 'fathom' in ancient times was eight feet; dry corresponds with axe, both being names of tools, 'dry'— an ancient type of weapon."
