The following content is only to reveal the common tricks used by criminals. The purpose is to help everyone be more vigilant and prevent the risk of theft, but it is by no means to teach how to commit crimes. On public transportation, the crowded and noisy environment provides "natural" conditions for thieves to commit crimes. They often use the following methods: 1. Division of labor and cooperation, team crime • A common method is that criminals are divided into two or more people to cooperate: one person deliberately attracts the victim's attention (such as chatting, creating disputes, asking simple questions or asking for help), while the other person takes the opportunity to get close and steal wallets, mobile phones or other valuables. 2. Deliberately create physical contact • In a crowded subway or bus, some thieves will deliberately get very close, take advantage of body friction or "accidental" collisions, and steal your personal belongings when you are not paying attention. 3. Use false requests for help to distract attention • Sometimes, thieves will pretend to be lost, have an emergency, or ask for help to carry something. At this time, you are very likely to be distracted because of sympathy or politeness, thus putting your wallet, bag and other valuables in danger. 4. Create chaos and distract attention • Some criminal gangs may work together to create some minor chaos or disputes (sometimes deliberately fabricated "street conflicts") to divert the attention of surrounding passengers. When the crowd is focused on the chaos, another member will take the opportunity to steal. 5. Take advantage of crowds • During rush hour or crowded conditions, many thieves will take advantage of the crowded environment to blend into the crowd and steal without obvious detection. At this time, tight clothing, open backpacks or unzipped zippers are particularly easy targets. Tips and suggestions: • Stay alert: On public transportation, try to keep an eye on your personal belongings and don't leave valuables in conspicuous places. • Watch your behavior: Don't overly trust strangers' requests, especially when the carriage is crowded and chaotic. • Improve storage security: Use a bag with a zipper or a secure design, and try to carry it close to your body. • Pay close attention to your surroundings: If you notice someone around you behaving abnormally or approaching frequently, try to maintain eye contact with other passengers in the carriage so that you can warn each other. Understanding these common methods and raising awareness of prevention will help reduce the risk of theft on public transportation such as subways and buses.
