HSK tests reward **recognition, correct tone, and natural placement** of common chengyu (成语). Expect them in reading, cloze, grammar/error items, and advanced writing. Use Chinese only for the chengyu; keep all explanations and strategies in English.
Chinese schools introduce chengyu (成语) steadily from primary through high school. Learners meet them in readers, dictations, cloze questions, and composition tasks. Use Chinese only for the idioms themselves, with pinyin; keep all explanations in English.
These MCQs mirror exam logic: map **function (praise/critique/warning/method)**, **tone/register**, **grammar slot**, and **connector cues**. Chinese appears only for the chengyu with pinyin when needed; all scaffolding is in English.
Cloze tests measure whether you can choose a chengyu (成语) that fits **logic**, **grammar slot**, **tone**, and **register**. Keep chengyu in Chinese with pinyin; all guidance is in English.
In exam essays, chengyu (成语) should clarify arguments—not decorate sentences. Use **one precise idiom per idea**, placed in the right grammar slot, with facts or analysis around it. Chinese only for the chengyu with pinyin; all coaching is in English.
