The legal person is the person in charge of the enterprise, and the shareholders are only the investors of the company. Generally speaking, the legal person of a company is the chairman (that is, the person who holds the most shares). Legal persons have the right to operate and manage, while shareholders are only investors and enjoy rights such as income. When signing a contract with other companies, only the signature of the enterprise legal person is valid. Shareholders are responsible for the company to the extent of capital contribution, and enjoy the rights of income distribution, major business decisions and selection of managers. The legal representative is the person in charge who exercises the functions and powers on behalf of the company, and his behavior constitutes the representative behavior of the company. He is engaged in activities within the scope of authority stipulated by laws, regulations and the company's articles of association, and may be the chairman or manager.

Article 490 of the Civil Code of People's Republic of China (PRC): If the parties conclude a contract in the form of a contract, the contract is concluded when the parties sign, seal or fingerprint it. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it. A contract shall be concluded in written form as stipulated by laws, administrative regulations or agreed by the parties. If the parties do not do this in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.
