Are the workers in Datuhe Coal Mine in Lishi, Shanxi regular workers?

Coal mine workers are not all regular workers, but also temporary workers. Regular workers have five insurances and one gold, while temporary workers don't necessarily have five insurances and one gold. Workers in coal mines are regular workers, contract workers and temporary workers. Formal workers must have five insurances and one gold, but some temporary workers have paid five insurances and one gold, and some have not paid five insurances and one gold.

This is because some temporary workers have short working hours and may quit within a month, so some temporary workers do not have five insurances and one gold.
