At large public gatherings or festivals, the environment is often noisy and crowded, which provides many advantages for thieves. Here are some factors that may be exploited to carry out theft: 1. **Crowds**: The high density of people can easily mask the thief's movements, allowing them to approach the victim without being noticed. 2. **Distraction**: Participants tend to focus on the performance, activities or interactions with others, while ignoring their personal belongings. 3. **Noisy environment**: Music, cheering and other background noise can mask the sound of zippers or bag buckles being opened, making it easier for thieves to succeed. 4. **Nocturnal activities**: In low-light environments, thieves' movements are less likely to be detected. 5. **Disguise and confusion**: Thieves may pretend to be ordinary participants, service staff or performers to reduce the vigilance of others. 6. **Sudden movements**: For example, someone deliberately creates a small conflict, push or fall, to distract the victim and take advantage of the opportunity to steal. 7. **Teaming**: Thieves often work in pairs, with one person responsible for distracting the target and the other for stealing. 8. **Obstruction**: Use large props, placards, or umbrellas to block the view, so as to carry out covert pickpocketing. 9. **Bait Strategy**: Deliberately drop something or ask for help to distract others from stealing. To avoid becoming a target of theft, you should be vigilant when participating in such activities, take good care of your belongings, and even use anti-theft backpacks or waist bags.
