中介 (zhōng jiè): выступать посредником

I wanted to rent an apartment close to my company, but I didn't have time to look at places myself, so I found an agency to help.

He met his current business partner through a friend who acted as an intermediary, and the two of them started a small company together.

When we were buying the apartment, the agent told us that the property rights were very clear, so we could sign the contract without worry.

This employment agency specializes in helping university graduates find jobs and does not charge job seekers any fees.

Because of the language barrier, he hired an intermediary to accompany him to handle his residence permit, translating and explaining each step.
