There's nothing wrong with it. Now that online second-hand transactions are so developed, everything is possible.

When buying second-hand Xianyu, it’s the same as Taobao transactions. It depends on the other party’s Sesame Credit, whether it has real-name authentication, whether there have been transactions before, other sellers’ evaluations of it, and whether there are any disputes. After you get the item, try it out first and make sure there are no problems.

Make sure you receive the goods and return them if there is any problem.

In fact, it is the same as Taobao.
