交谈 (jiāo tán): to chat, to converse

Two old friends chatted happily in a café until it got dark.

After the meeting, the manager talked with the client in English for half an hour and discussed the specific details of the cooperation.

Because they didn't share a common language, they could only communicate using gestures and simple words.

On the train, an elderly person next to me started chatting with me and told me stories from his youth.
