How it works
The adverb '大为' (dà wéi) is used in formal or written Chinese to indicate that an action or state has reached an intense or significant degree. It is typically followed by disyllabic (two-character) verbs or adjectives that express psychological states, reactions, or changes.
Examples

Common mistakes
Do not use '大为' with monosyllabic (single-character) words; for example, say '大为改观' instead of '大为改'.
Tip
Think of '大为' as a more formal alternative to '非常' or '很大程度上', specifically used to highlight a significant impact or a strong mental reaction.
