The authorized person of the company can only be a legal person, not someone else. At this time, the principal is a legal person. If authorized by the legal representative, the principal is the legal representative, and the legal representative shall be responsible for the matters handled by the trustee, not the legal person.
Article 3 of the Company Law stipulates that a company is an enterprise legal person with independent legal person property and legal person property rights. The company is liable for its debts with all its property. Shareholders of a limited liability company shall be liable to the company to the extent of their subscribed capital contribution; Shareholders of a joint stock limited company shall be liable to the company to the extent of the shares subscribed by them.
