Isn't Luckin Coffee certified and paid?

Luckin Coffee has no authentication and payment. In terms of salary, it is the same as the part-time job in the store. I certified the barista for 26 hours before the certification. Luckin Coffee's salary is paid in two installments. One was sent on the 5th of the following month, and the other was sent on the 20th of the following month. Luckin Coffee is paid twice a month, from 20th 1 to 15, and from 5th 16 to 30 the following month.
