This topic examines the board of supervisors. A limited liability company with a small number of shareholders or a small scale may have only one or two supervisors instead of a board of supervisors, which is wrong. The board of supervisors of a limited company shall include an appropriate proportion of shareholders' representatives and employees' representatives, among which the proportion of employees' representatives shall not be less than 1/3, and the specific proportion shall be stipulated in the company's articles of association. B is correct. The board of supervisors of a limited company shall meet at least once a year, and the supervisor may propose to convene an interim meeting of the board of supervisors. C error. The resolution of the board of supervisors should be passed by more than half (not "more than half", more than half excluding the number, more than half including the number) of supervisors (all, not "attending the meeting"), D error.
