When you ask, "Can I get unemployment benefits when I retire at 50?" The answer to this question is yes, but only if you meet certain conditions. First of all, you need to pay unemployment insurance at the employer for one year. This is one of the basic conditions for receiving unemployment benefits, as unemployment insurance is designed to cover those who are unable to make ends meet due to unemployment. 
Second, you need to make sure that your departure is not due to personal reasons. This means that if you leave your job for personal reasons, such as resignation, dismissal, etc., you will not be able to apply for unemployment benefits. However, if you leave your job because of company layoffs, company bankruptcy, etc., then you are eligible to file for unemployment benefits. As for how to apply for unemployment benefits, you can check with your local social security office. They will tell you in detail what documents you need to prepare and the specific application process. Usually, you will need to provide your ID card, social security card and other relevant supporting documents, and fill out an unemployment registration form. The Social Security Administration will then review and decide whether to approve your application. 
It should be noted that the receipt of unemployment benefits is for a certain period of time, generally not more than two years. Therefore, before applying for unemployment benefits, you need to think about your specific situation and your future career plans. At the same time, you will also need to attend training and interviews with the Social Security Administration on time during your unemployment benefit period to maintain your unemployment status and eligibility. In short, if you are eligible, you can receive unemployment benefits after you retire at the age of 50. However, it should be noted that there are certain conditions and procedures that need to be met to apply for unemployment benefits, and the period for receiving unemployment benefits is limited. Therefore, you need to carefully consider your own situation and consult the relevant regulations and procedures of the local social security bureau before applying.
