Buddhism has deeply influenced 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).
usage
佛 is pronounced 'Fó' when meaning Buddha, but 'fú' in the word 仿佛 (fǎngfú, 'as if').
usage
佛系 (Fó xì, 'Buddha-like') is modern slang meaning laid-back, not caring about outcomes — a very popular term among young Chinese.
