1. When encountering strangers knocking on your door to sell products or offer water, electricity, gas, or insurance services, be sure to handle the situation with caution. If you have no intention of purchasing the products or services offered, you may politely decline. Avoid any verbal or physical conflict with the individual.
2. If you find the person's behavior suspicious, try to note their main characteristics, such as height, build, age, skin color, accent, and clothing. Report the incident to the police as soon as the person leaves.
3. Some criminals may use pretexts such as emergency gas, electricity, or water inspections, or even urgent mail delivery, to gain the homeowner's trust, enter the house to commit theft, or even cause physical harm. Do not easily trust such excuses, as utility companies for gas, water, and electricity will always notify residents in advance before starting work and will never show up without prior notice. Furthermore, UK postal services do not deliver mail or packages in the evening.
4. Some individuals may ask to use the restroom or come inside for a drink of water during their sales pitch. In such cases, you must be extra cautious; it is best not to let them into your home.
5. If the person is persistent and you find it difficult to handle alone, you can ask a neighbor for help; after all, there is strength in numbers. It is worth noting that Chinese people are accustomed to keeping their doors closed and, due to cultural or language barriers, may not interact much with neighbors. This lifestyle and mindset should be adjusted.
6. If you wish to avoid being bothered by various salespeople, you can post a note on your door that says, "I do not accept any solicitations, please do not disturb." Most door-to-door salespeople will see the note and leave accordingly.
