What are the working hours of Qihe Shandong Laigang Yongfeng Iron and Steel Plant and how to shift?

The three shifts here are on Mondays, that is, the day shift is one week and the shifts are on Saturdays. For example, I work the day shift this week, get off work at 0/6: 00 on Saturday, work the night shift at 23: 30 on Saturday, work the last night shift on Saturday, and work the middle shift at 0/5: 30 on Sunday. The middle shift lasts for another week, and the middle shift is finished on Saturday night, and then the day shift starts at 7: 30 on Sunday morning, so the shift is changed, that is, the third shift shifts twice and the big shift closes once, understand?

I work in Yongfeng now. I used to work in three shifts, but now I work in a long day shift.
