It means to use a trading platform, such as Taobao.

Take the platform. Many people will collect some of their idol’s past merchandise. But it’s easy to be cheated if you don’t use the platform. Using a platform means using a professional third-party guaranteed trading platform. Buying and selling through formal channels is relatively safe and reliable, and you are guaranteed not to be cheated. For example, you want to buy or sell things to other people, but you don't dare to send money directly to others, for fear that they will take the money and block you directly. So I want to use Xianyu as a third party. One of them posted his product on Taobao or Xianyu, and the person who wanted to buy it directly took the photo and paid through Taobao or Xianyu, and then the person who posted it shipped it to him. This way, with Taobao as a guarantee, he can feel relieved. trade.
