The key to designing a seemingly ordinary text message that actually contains a vague warning is to embed hints or puns in the superficial information so that the recipient can understand the literal meaning and perceive the potential information when reading it. . Here is an example： --- **SMS content：** “Hi, the weather has changed a lot recently, remember to wear more clothes and don't catch a cold. Be careful when you go out recently. I heard that some places nearby are not very safe, especially at night. Take care of yourself and don't let me worry. ” --- **analysis：** 1. **Superficial information**: This text message seems to be concerned about the health and safety of the other party, reminding the other party to pay attention to weather changes and night travel. 2. **Vague warning**: By mentioning “weather changes” and “unsafe places”, it is implied that there may be potential dangers or threats. At the same time, the phrase “Don't make me worry” also conveys a sense of urgency, making the other party aware of the need to be vigilant. --- **Design points：** 1. **Natural and smooth**: The content of the text message should be as natural as possible, avoiding being too abrupt or direct, so as not to cause unnecessary suspicion. 2. **Puns or hints**: Embed some puns or hints in ordinary information so that the recipient can perceive the potential information. 3. **Emotional resonance**: By expressing concern or concern, it is easier for the other party to accept and understand the warning meaning. --- In this way, text messages can not only convey daily concerns, but also cleverly remind the other party to pay attention to potential dangers, so as to achieve the purpose of vague warnings.
