Bo Huang is going to steal Lao Zhao's money. Suppose a time: he is going to steal from Lao Zhao's office building at night12: 00. At this time, Bo Huang, as a thief, will create the illusion that he is still with Lao Zhao at night12: 00, so he will adjust the clock to12: 00, which is actually just/kloc. But Lao Zhao thinks it's12: 00, and Bo Huang is still with himself! When Bo Huang came back after stealing, the actual hour was12: 00, and Bo Huang was putting the clock back. Because the other party had taken drugs and didn't know the time, he got up and looked at it at12: 00, so he thought that Bo Huang had been there! There is no time to commit crimes!
