If you want to avoid in-depth conversations while being polite when visiting a construction site, you can refer to the following suggestions： 1. **Plan your itinerary in advance**: Clarify the purpose of the visit, sort out key issues, plan your stay time, advance the process as planned, and reduce temporary communication needs. 2. **Keep smiling and being polite**: Always show a friendly attitude, use smiles and simple greetings to create a relaxed atmosphere, so that the other party feels kind, but does not open the topic too much. 3. **Focus on observation and recording**: Focus on observing work scenes and recording key information, nodding or responding briefly in a timely manner to indicate that you are listening without triggering an in-depth conversation. 4. **With the help of accompanying personnel**: If there are people in charge of the construction site or accompanying personnel, communicate with them more, obtain information through them, and reduce direct dialogue with ordinary construction workers. 5. **Prepare specific questions**: Prepare targeted, concise and clear questions in advance to avoid long discussions caused by open-ended questions, and stop in moderation after getting the answers. 6. **Pay attention to the way you ask questions**: Use closed-ended questions, such as “Is there a fixed length of time for this job every day?" “Only the other party needs to answer short answers such as ”yes“ or ”no" to limit the depth of communication. 7. **Choose the timing of communication**: Choose the workers to have a simple communication between breaks. At this time, everyone may be busy and tired. Short communication will not cause disgust, and in-depth conversations can be avoided. 8. **End the topic in a timely manner**: When the exchange comes to an end, find a suitable reason to end naturally, such as “I'll go to other places to have a look, and then talk”, to avoid the other party from continuing to delve into the topic.
