I bought 15 social security in the mainland. Can I buy social security when I enter Tibet?

A person can only have one social security, and it is impossible to pay two social security at the same time. You cannot pay a social security during the payment period.

Social security is a system in which the state or the government is the main body, and through the redistribution of national income, citizens are given material help when they temporarily or permanently lose their ability to work and have difficulties in life for various reasons, so as to ensure their basic livelihood. The essence of social security is the pursuit of fairness, which must be based on legislation or law. Its basic contents include social insurance, social relief and social welfare.
