Chairman Mao said:
This tiny sphere,
  Finds a few flies here and there,
  Darting against wall
  Humming drops of tear!
  Ants only assume their colony a big state,
  Mayflies just can’t do the giant tree toppling.
  The west wind scatters leaves on the capital street,
  Now like flying arrows twanging.
  The whole world rolls on,
  With so many urgent deeds to be done
  As time presses, seize the day seize the hour!
  For Ten thousand years would be too long.
  Four Seas‘re surging with clouds and waters raging,
  Five Continents‘re rocking with wind and thundering.
  Wipe out all pests,
  We are always winning!
you a fly is a nuisance 你這個大假西 小蒼蠅
