I'm not familiar with how a table of people enlivens the atmosphere.

Others are just like you, so you don't have to be too formal. Better drink some wine and pry everyone's mouth open. Since you don't know anyone, let's meet.

First, let's start with introducing ourselves. It's simple: name, job position (or industry), everyone takes turns. You can also take part in a small game and randomly check to see if you still remember other people's information. If you can't answer, the two of you should talk it over. Secondly, ask the person you are interested in to introduce his or her occupation and find something from the conversation to let him or her play. I think the topic is open.
