Is it difficult to control the secondary key units well?

1, great work pressure: Level II key units need to deal with complex work tasks and emergencies, and central controllers need to be vigilant at all times to deal with various emergencies, which will bring great pressure.

2. Long working hours and night shifts: Many secondary key units need to run 24 hours, so the central controller needs to work long hours and night shifts. Working for a long time will cause physical fatigue, disrupt the law of life and bring trouble to the central controller.
