What is the English original of 精致的平庸?
I agree with  user3306356.


  Liu (2010) characterises as ‘exquisite mediocrity’(精致的平庸) the kind of
  research that is centred on determining the accuracy and elegance of
  norms and procedures rather than on creating something of functional
  value to society.
