According to Article 25 of the Company Law, shareholders should sign the articles of association for confirmation, so it is obvious that the articles of association are agreements between shareholders. The articles of association are the most effective documents of the company. It is a general principle to stipulate in the articles of association who decides the investment guarantee and other matters, which should be freely agreed, which is also proved by the provisions of Article 16 of the Company Law. However, for listed companies, the CSRC may have some specific regulations, so it is up to the shareholders' meeting or the board of directors to decide whether to abide by their regulations.
Therefore, depending on the nature of your company, a general limited liability company can make an agreement on its own in its articles of association, as long as it does not violate the direct prohibition provisions of the company's laws and regulations (for example, Article 38 clearly stipulates that some rights are in the shareholders' meeting).
