A large enterprise discovered an issue with empty boxes on its soap packaging production line. To solve this problem, they hired a postdoctoral fellow in the field of automation, formed a research team, and used high-tech methods such as mechanics, microelectronics, automation, and X-ray detection. They spent hundreds of thousands of yuan to successfully design a system for detecting and removing empty soap boxes. At the same time, a township enterprise also encountered the same problem. Their boss placed a fan next to the production line and used the wind to blow empty soap boxes away from the production line, with a total cost of 20 yuan. A few years ago, when Huobi voted to register, a video was taken to prove that you voted and sent it to the boss. Then the boss's payment process was very mature. Can a project that looks impressive and full of professional jargon for ZK's concept really solve bribery? That is to say, we should guard against gentlemen but not against villains.
