Does Lianyungang have to force the social security card and salary card to be combined into one?

It's not mandatory. The Social Security Card of the People's Republic of China is an integrated circuit card, which is uniformly planned by Ministry of Human Resources and Social Security and issued to the society by local human resources and social security departments, and used in various business fields of human resources and social security. Lianyungang city does not force the social security card and salary card to be combined into one, and the social security card has a wide range of functions. Cardholders can not only use the card for real-time settlement of medical insurance personal accounts, but also handle pension insurance affairs, job registration and unemployment registration procedures.
