HSK 5 is generally considered to correspond to the B1 level of the CEFR (Common European Framework of Reference for Languages), rather than C1.

- HSK 5 Proficiency: At this level, learners can understand and use 2,500 common Chinese characters, engage in complex communication, read moderately difficult articles, and write simple written content. They can handle routine language tasks in work or study, describe experiences, express opinions, and participate in in-depth discussions on topics such as social issues and cultural differences. However, their ability to discuss abstract topics precisely is still limited.

- CEFR B1 Level: The B1 level in the CEFR framework represents an intermediate language proficiency. Learners at this level can understand the main points of clear standard input on familiar matters regularly encountered in work, school, leisure, etc. They can deal with most situations likely to arise while traveling in an area where the language is spoken. They can produce simple connected text on topics that are familiar or of personal interest, and can describe experiences and events, dreams, hopes, and ambitions, and briefly give reasons and explanations for opinions and plans.
- Comparison: While both HSK 5 and CEFR B1 represent intermediate language proficiency, there are some differences in the specific skills and abilities they emphasize. HSK 5 places more emphasis on reading and writing skills, as well as the ability to understand and use a relatively large vocabulary. CEFR B1, on the other hand, provides a more comprehensive description of language proficiency across all four skills (listening, speaking, reading, and writing).
