4. Cultural Background and Notes

• The phrase has roots in classical literature, notably the 'Epitaph for Mr. Zhenyao' (贞曜先生墓誌銘) by the Tang Dynasty poet Han Yu (韩愈), which used the phrase 间见层出 (jiàn xiàn céng chū) to describe things appearing in layers. It also draws from the History of Song (宋史), specifically the biography of He Ji (何基), which used the phrase 愈出不穷 (yù chū bù qióng).
• In modern usage, it is highly versatile. While it can describe negative things like 犯罪手段 (fàn zuì shǒu duàn - criminal methods), it is frequently used to praise 创新 (chuàng xīn - innovation) and 人才 (rén cái - talent). However, it is never used for static quantities; for example, you wouldn't use it to say there are many trees in a forest unless the trees were magically popping up one by one.
