Does it count as social security time for postdoctoral students studying abroad to settle in Shanghai?

The length of service of domestic doctoral students is calculated during the study period, but it is not social security.

During the doctoral period, it is counted as 3 years of service, but it is not counted as social security and payment period. No matter how many years the doctor is postponed, he will only serve for three years. Now the length of service and social security are separated, and the length of service without social security is basically useless. The concept of length of service will only be used in paid vacations and recuperation days, as well as the salary scale within the system.
