What do corporate and natural person shareholders mean?

don't listen to the jokes of the first two.

enterprise legal person is a legal term. In the civil legal relationship, an enterprise needs to have a virtual personality, and bear the responsibilities of creditor's rights and debts, so an enterprise legal person is just a legal concept of an enterprise, not a real "person".

when an enterprise as a legal person exercises its rights, there is a real natural person as the representative, which is what we call the "legal representative of the enterprise".

a natural person shareholder refers to the investor of a company, who is a natural person, not another enterprise legal person.
