Is it legal for the company to plan frequent shutdowns?

1. As long as there is no post stipulated in the contract, the company can adjust the post according to the situation. Otherwise, this is impossible.

If the company can adjust the post according to the contract, it can't reduce the salary. Otherwise, it is illegal.

The company asked you to take two days off the day before. It is also illegal if your wage income is reduced and below the local minimum wage. Otherwise, it is ok.

Some netizens posted the minimum wage standard for you, so I won't repeat it.
