Comparison section · original #5 · level order #98
How it works
Both 对 (duì) and 对于 (duìyú) can introduce the target of an attitude, opinion, or action.
对 (duì) is shorter, more common, and more natural in speech.
对于 (duìyú) is more formal and common in writing or structured explanation.
Example sentences

Key point
