So I got out of the car and walked to the security booth at the back entrance of the building. There are several screens in the security booth watching the building's every move. It's just that the security guards guarding these screens didn't look at the screens at all, but ate small dishes and drank small wine outside the security booth. It's really irresponsible! If he had been in charge, we would have reacted to someone on the screen when we came out of there yesterday. I stepped forward and said, "Big brother, just now."
