2. Dealing with the thief: I happened to bump into him. The first important thing is to remember his appearance and basic characteristics. It is convenient to go to the inspection bureau to solve puzzles when a criminal case occurs. Of course, it would be better if there is a camera in the place. The second is simply to talk to him. Don't be afraid of him. It is not difficult to strike up a conversation with strangers. Everyone is human and can talk. Ask him casually. If he is a thief, his heart will be very fragile, which will increase his pressure and lead him to appear. The third is to quickly scan the surrounding doors and windows with your eyes to see if there are signs of thieves entering. It is important to quickly see if a thief has entered your home, so as to catch the thief at the first time. Fourth, see if the thief has other items besides moon cakes, such as computers and many mobile phones. If so, you can pretend to be the landlord of this house or the security guard and property of the community and ask him why he is here.
