Question about Database Design mysql

The requirement should be as follows: the system has a default product table, but the default product table is for merchants; that is to say, merchants can register products and dismounted products in the default product list of the system. The prices of products can only be modified... the requirement should be as follows:

The system itself has a default product table;

However, the default product table is for merchants;

That is to say, merchants can register products that can be shelved in the system's default product list. The product price can only be changed;

How should we design the table of products that have been shelved by merchants, products that have been dismounted, and default products of the system,

How can I associate the shelved products and dismounted products of each registered merchant with the default system product table?

Do not copy a system product table to the product table of each merchant. In this way, 100 merchants have 100 product tables.

How can we store data;

System information;

One of the two identities of the platform is a registered merchant, which can only sell the system's own products. That is to say, the merchant can check whether the product has any flowers to mount the system's products and modify the product price; one is to register a product purchase user; the user can purchase the product of the merchant

The background of the merchant is to display that all products of the system can be shelved. The prices of system products can be modified when the products of the system are shelved.
