There is no legal time limit for this. Because of the needs of production and operation, there is no limit on the number of equity transfer within one year, and it is impossible for the law to prohibit it, because if it is prohibited, it will conflict with the equity transfer right of equity. The articles of association of a limited liability company may restrict the transfer of shares, but it shall not violate the mandatory provisions of the law (Article 72 of the Company Law). No restrictive provisions shall be made in the articles of association of a joint stock limited company.
