Can retirement pension insurance be opened normally after entering Korea?

Can retire according to the policy. Take Xiamen as an example: According to the opinions of Xiamen Human Resources and Social Security Bureau on issues related to basic old-age insurance, Xiamen Renshe [2013] No.34, the first point is that people who have left the country to settle down, who originally had household registration in our city and participated in the basic old-age insurance for enterprise employees as household registration personnel in our city, can go through retirement procedures and enjoy old-age insurance benefits in accordance with the relevant regulations of our city. Residents of Taiwan, Hong Kong and Macao who are employed in Xiamen or foreigners who are employed in China participate in the basic old-age insurance for enterprise employees in our city, and the payment period formed can be combined with the payment period of the original enterprise employees who participate in the basic old-age insurance for enterprise employees in our city as residents of this city.
