Can I get a pension in Shenzhen when I buy social security at the age of 42?

Of course. According to official website information of Shenzhen Social Security Bureau, 42-year-old people who buy social security in Shenzhen can receive pensions continuously. The household registration requirement in Shenzhen is that you have paid social security 15 years in Shenzhen continuously and have a household registration record in Shenzhen before you are eligible to receive a local pension. For non-Shenzhen residents, they need to meet the requirements of the number of years to pay social security in the local area before they can apply for pensions.
