You can indeed choose to pay social security on Taobao after leaving your job, but this is not the only option. Specifically, there are several ways to pay social security on behalf of others:

Find a payment company on Taobao or other online platforms: These companies usually provide social security payment services. You only need to pay a certain fee and they will help you deal with the social security payment. But it should be noted that you must be cautious when choosing this method to ensure that the payment company you find is legal and reliable.

Find a local talent center or street office: If you are a local hukou, you can consider transferring your social security relationship to the talent center or street office to pay. In this way, you can bear all the social security premiums as an individual, but you can usually only choose to pay three or four insurances, not the full five insurances.

Find a formal social security payment company: If you are not a local hukou, or you find it troublesome to handle social security payments on your own, you can find some formal social security payment companies to handle it. These companies usually provide more comprehensive and professional services, but you also need to pay a certain service fee.

Whichever method you choose, you need to pay attention to the following points:

Ensure the legitimacy and credibility of the payment company or institution to avoid being deceived or causing other disputes.

Understand the specific content and fees of the payment to avoid unnecessary trouble.

Pay attention to your social security payment in a timely manner to ensure that your social security rights and interests are not affected.
