可能 (kěnéng) — use '八成' for a stronger certainty compared to '可能', which indicates mere possibility.

Think of '八' (bā) which looks like a pair of glasses, representing the '80%' as you see things clearly. The '成' (chéng) can be imagined as a building block, suggesting that you are building up your confidence in an outcome. Together, visualize putting on your glasses to see that something is '80% likely' to happen.

Learners often confuse '八成' with other percentage expressions like '六成' (60 percent) or '五成' (50 percent). It is usually used in informal settings, so avoid using it in formal writing. Be mindful of the tone; saying '八成' with a rising tone may lead to misunderstandings.

At HSK Level 7, focus on using '八成' in various contexts, such as making predictions or expressing opinions. This term connects to other probability-related terms you may have learned, like '一定' (yídìng, definitely) or '可能' (kěnéng, possibly), enhancing your ability to discuss likelihoods.

'八成' is often used in discussions around decision-making in business contexts. In Chinese culture, expressing certainty can be seen as confidence, so using this phrase can convey a strong belief in your statement during negotiations or planning.

Learners may mistakenly use '八成' to mean '80%' in a mathematical context, which is incorrect. Instead, it should be used to express likelihood, as in '他八成会来' (He is most likely coming).
