When can I report that job-hopping in Shanghai will not affect social security?

The work change of Shanghai 15 newspaper does not affect social security. General units will take no. 15 is the dividing line. Did the employees who joined before 15 pay the social security of the current month, but the employees who joined later did not. 15 did not pay social security in the current month. Employees who leave before 15 will not pay social security for the current month, while employees who leave after 15 will pay social security for the current month.
