I wonder what people who live in factory dormitories should talk about at work.

1. Try to actively communicate with workers. If you are interested, you can ask some questions to your colleagues or talk about your hobbies. This can help you to establish contact and friendship.

2. Join the chat group of colleagues. If your factory has a colleague chat group, you can join this group to chat with the workers.

3. Participate in social activities in the factory. If the factory holds social activities, you can take part in these activities and communicate with the workers.

4. Try to participate in the trade union activities in the factory. If there is a trade union in your factory, you can participate in the activities of the trade union and communicate with the workers.

5. Have lunch or tea with colleagues at work. During the break of working hours, you can have lunch, tea and chat with your colleagues.

I hope these suggestions can help you.
