座谈 (zuò tán): avoir une discussion informelle

In order to understand the students' true thoughts, the principal decided to hold a symposium and let each class send representatives to have an informal discussion.

At last week's literature symposium, the writer and readers sat together and had a relaxed discussion about their insights on novel writing.

Senior management and employee representatives have an informal discussion once a month to talk about problems encountered at work and suggestions for improvement.

Yesterday afternoon, several experts were invited to the community to have a face-to-face discussion with residents about the practical difficulties of garbage sorting.

Through this informal discussion, both sides cleared up their misunderstanding and agreed to have another discussion next month to settle the specific details of their cooperation.
