Legal analysis: whether it is a company act or an individual act depends on the authority of the legal representative in the company's articles of association. Only the signature within the authority is the behavior of the company, and the behavior outside the authority is naturally the behavior of the individual. In addition, if you sign a contract with foreign countries, you need an official seal to identify the company's behavior.

Legal basis: Article 50 of the Civil Code of People's Republic of China (PRC), a contract concluded by the legal representative or person in charge of a legal person or other organization beyond its authority is valid, except that the other party knows or should know that it is beyond its authority.

Article 61 The restriction of the legal representative's representation by the articles of association or the functions and powers of a legal person shall not be against the bona fide counterpart.
