Mastery means hearing the ** undertone** behind the four characters: polarity (praise/critique), strength (mild → strong), register (colloquial ↔ literary), typical collocations, and context (business, media, literature). Use Chinese only for chengyu with pinyin; keep all guidance in English.
Fluent writers use fewer, better chengyu (成语). This lesson shows **what to avoid**, how to **repair** misfires, and how to **limit frequency** without sounding flat. Use Chinese only for the idioms (with pinyin); keep all guidance in English.
Build a living, searchable bank of chengyu (成语) that fits your voice and goals. Keep idioms in Chinese with pinyin; store meaning, tone, grammar slot, and one authentic example. Review little and often.
Native-like fluency with chengyu (成语) shows up in **when** you use them, **which** one you choose, **where** you place it in the sentence, and **how lightly** you let it sit. Use Chinese only for the chengyu (with pinyin); keep all guidance in English.
