College students must go to the pig farm in advance to enter Wen's service department.

Not necessarily. Shi Wen Service Department is a subsidiary of Shiwen Group, mainly engaged in pig farm management, breeding technology and other services. For some positions related to pig farms, employees may need to have relevant farming knowledge or experience, so they need to study or practice in pig farms first. Other positions unrelated to pig farms do not necessarily need to be advanced to pig farms. Specific requirements will vary according to different positions.
