There are indeed some factors that thieves may exploit to conduct stealthy thefts during large public gatherings or festivals. Here are some common factors: 1. **Crowds**: Crowded places are easy to confuse people, and thieves can use the crowds to approach and escape, reducing the chance of being discovered. 2. **Distractions**: At festivals, there are various activities, performances and noises, which may distract people and make it easier for thieves to succeed. 3. **Temporary stalls and exhibition areas**: There may be many temporary stalls at celebrations, which lack security surveillance and become targets for theft. 4. **Unnoticeable contact**: Thieves may use the crowded crowds to take the opportunity to approach the target and steal. In a crowded environment, a slight bump or contact is not likely to arouse suspicion. 5. **Concealed escape routes**: At large events, there may be many exits and escape routes, and thieves can find unnoticed routes to quickly leave the scene. 6. **Pretend to participate in activities**: Some thieves may pretend to participate in activities or play to reduce the risk of being identified by blending into the crowd. 7. **Be familiar with the environment**: Some thieves may explore the event venue in advance to understand the layout and traffic flow in order to plan the theft. 8. **Use obstacles**: Use surrounding objects (such as stalls, furniture, etc.) as cover to hide their actions and whereabouts. 9. **Teamwork**: Some thieves may form teams to divide the work, with some people distracting while others carry out the theft. 10. **Use false identities**: Some thieves may pretend to be staff or volunteers to gain trust and get close to their targets. To protect property at large public events, people are advised to be vigilant, keep personal belongings safe, and pay attention to the surrounding environment and suspicious behavior.
