Buddhism has deeply shaped Chinese culture. Many everyday idioms come from Buddhist concepts:
放下屠刀,立地成佛 (put down the butcher's knife and become a Buddha on the spot — it's never too late to mend);
临时抱佛脚 (to clutch the Buddha's feet at the last minute — to cram). Modern slang gives
佛系 — "Buddha-style" — meaning laid-back, whatever-happens-happens.
