At present, there is no pension system in Hong Kong. In recent years, the social security system of "compulsory provident fund" has been implemented. To put it simply, the employer and the employee each have 5%, and a qualified investment company is appointed to be responsible for the investment. When the money is accumulated to the age of 65, you can take as much as you want.
Legal basis:
Mandatory Provident Fund Schemes Ordinance II. Enable MPFA to charge the approved trustee a statutory annual fee equivalent to 0.03% of the net asset value of the MPF scheme on January 1, 2002.
