Tips
usage
Positive — associated with scholarship, art, and careful career-building. Near-opposite of 急于求成 (eager for quick success). Often as topic or predicate: '贵在厚积薄发' / '做到厚积薄发'.
memory
厚 (thick / deep) + 积 (accumulate), then 薄 (thin / sparing) + 发 (release). A big reservoir that releases in a trickle — quality over quantity, depth over speed.
