Why does Nanshan Siemens MRI general worker recruit people every day?

I'm so tired. Nanshan Siemens MRI General Worker is a wholly-owned subsidiary of Siemens Medical, located in Shenzhen High-tech Industrial Park, and is a high-tech enterprise specializing in the production of medical magnetic resonance imaging systems. Because I was too tired at work, I basically left after a day's work, and I could only recruit people every day.
