Word list, levels, pinyin, part of speech

From the vocabulary section of the HSK Syllabus (《HSK考试大纲》, Center for Language Education and Cooperation, released November 2025, implemented July 2026): 11,000 entries with level, pinyin and part of speech. We list these facts so learners can study for the exam; the syllabus document itself is not reproduced. Yuloy HSK is not affiliated with CLEC or Chinese Testing International. Pinyin in the official list shows tone changes for 不 and 一 (for example bú kèqi).
