Why is it free to check the recruitment information in the factory and some are not?

The rule of the factory is to collect points when inquiring about information of special jobs, such as welders, electricians, forklift workers, polishers and porters. Other general factory information can be viewed free of charge, 10 times a day (30 times in total), and points will be deducted if it exceeds the number of times. For the latest information about the factory, please go to the home page to find a job-factory general worker.
