用心敷衍
[yòng xīn fū yăn]
The phrase means 'giving earnest efforts to perfunctory'. It seems paradoxical at first glance as ‘earnest’ is used for describing doing things in a diligent and serious manner while 'perfunctory' indicates handling affairs superficially without putting real effort. Thus, this nickname may reflect a complex emotional state that one tries to be serious about something inattentive or meaningless.
