Matter comes in countless varieties,
 And the forms are evershifting, as well.
 Writers must dance the varied characters
  To dulcet lines where elegance dwells,
 Finding the right pace, cadence, and stresses
 To blend like harmony in the five hues.
 Though the tune fades in and out randomly
  And the path is rugged and hazard-strewn,
 Those who know the ways of change and order
  Will find all falls into place with a flow.
 But if one misses the proper pivots
  It's like grabbing the tail to steer the nose --
 Like yellow painted onto wet, black walls,
  One's writing becomes muddy, and it stalls. 

The original in Simplified Chinese:

其为物也多姿，其为体也屡迁。 
其会意也尚巧，其遣言也贵妍。 
暨音声之迭代，若五色之相宣。 
虽逝止之无常，固崎锜而难便。 
苟达变而识次，犹开流以纳泉。 
如失机而后会，恒操末以续颠。 
谬玄黄之粗叙，故浍涊而不鲜。
