You ask too many questions, so I will answer you in one sentence: as long as it is a cashier's job, it is not easy to do, especially in supermarkets.

As for Meitehao, the salary is paid monthly. The probation period is three months, and the salary is not high, even if there is insurance, it is the lowest. The salary after investment is not high enough. The rest are arranged in shifts. Generally, you can take one day off a week, but it is not necessarily that day. That's all I know.
