Tips

history
From a Ming-dynasty jab at exam culture recorded in 《杂志》: candidates memorized set phrases just to pass the imperial exam — 'bricks used to knock the door open and then tossed aside once you're through.' Modern Chinese keeps both senses: a neutral 'entry ticket' and a slightly cynical 'disposable credential.'
register
Neutral to mildly pragmatic. Works for diplomas, certifications, a debut work, or any initial proof of eligibility.
