After a shareholder contributes to the company and becomes a shareholder of the company, the shareholder's contribution becomes the property of the company. Shareholders want to quit the company. In the absence of law that shareholders can ask the company to buy back shares or the company is facing dissolution and liquidation, shareholders' withdrawal of capital contribution will constitute the withdrawal of capital contribution in the Company Law. Withdrawing capital contribution is an act explicitly prohibited by the Company Law. Where a shareholder withdraws his capital contribution, he shall bear supplementary liability for compensation to the company's creditors within the scope of withdrawing his capital contribution principal and interest.

If the shareholders of the company want to withdraw from the company and recover part of their capital contribution, the legal way is to transfer the company's equity to other shareholders or a third person other than the company's shareholders, so as to achieve the purpose of withdrawing from the company and recovering their capital contribution. If, as mentioned in the question, each of the 90 shareholders of the company withdraws part of its capital contribution on average, all 90 shareholders will withdraw their capital contribution. The creditors of the company may require 90 shareholders to bear supplementary responsibilities for the debts that the company cannot pay off within the scope of withdrawing the principal and interest of capital contribution, which is really not desirable.
