私人有限公司,小股東想退股,而又找不到認購人.有何方法取回投資金額,(部份金額也可)

There is no other way. You can ask the other shareholders to give you an offer. It is quite difficult to get an outsider to buy the shares from you unless he is quite happy with the company's financial position and its profitability.
Moreover, you have to get the other shareholders to buy the shares from you first at the same offered price before you can sell it to an outside shareholder ( Pre-emptive Clause ). This is the requirement of a private limited company as stated in the Articles of Association of the company and the Companies Ordinance.
