The design of such text messages requires a balance between daily language and hidden information to ensure that the recipient can perceive potential warnings, while onlookers only think it is ordinary communication. The following are some ideas and examples： ### Core strategy： 1. **Pun metaphor**: Use weather ("Storm warning"), life scenes ("Check doors and windows") or common experiences as code words 2. **Abnormal details**: Add elements that do not conform to the context to the normal content (such as mentioning air conditioning failure in the bitter winter) 3. **Numeric password**: Pass information through a specific combination of numbers (such as the agreed time code) 4. **Emotional displacement**: Wrap warnings in a caring tone, such as reminding health but actually warning personal safety ### Scene example： **Workplace warning** "Mr. Wang, the flowers for the 20th meeting you ordered have been confirmed, but the flower room reminds you that the rose thorns have been particularly sharp recently. It is recommended to choose lilies instead. Do you need to adjust now? " (Hint: The original plan for the 20th is risky, it is recommended to change the plan) **Family code words** "Mom, remember to take antihypertensive medicine every day. Don't exercise in the morning if the smog is heavy recently. My cousin said that the circuit of the old house should be overhauled, so I asked an electrician to take a look at it this weekend. " (Ostensibly concerned about health, but in fact warning to stop a certain dangerous behavior/there is a health risk) **Interpersonal early warning** "I put away the "Kite Chaser" you left in the company, but recently the administration department is cleaning up personal belongings before March. " (Pun reminder: There are sensitive items that need to be dealt with as soon as possible/someone wants to investigate you) ### Design essentials： 1. First clarify the core warning messages to be transmitted (such as: evacuate/stop contact/there is monitoring) 2. Select specific things that the recipient can associate with (co-raising pets, co-reading books, specific date events) 3. Add at least two contradictory points to enhance suggestibility (example: remind to check the heating pipe in summer) 4. Keep the open ending to prompt the other party to ask questions ("See you for details"/"See you in the old place") **Advanced skills**: Bury "abnormal repetitions" in text messages, such as using three periods in a row, or inserting mismatched emoticons in normal paragraphs (winter️️emoticons followed by umbrellas), this kind of cognitive conflict will trigger the recipient's alertness. Finally, be sure to test: let unrelated people feel completely normal after reading it, and at the same time make sure that the recipient can pass the decoding of your agreed secret language system. Historically, real spy text messages often used "mentioning non-existent items" or "reversing the logic of time" to achieve this effect.
