1, advertising difference: There are many products endorsed by anchors on the live broadcast platform, and the bracelet material is not marked to emphasize the advertising effect of the products and attract consumers' attention.

3. Unwilling to disclose trade secrets: the live broadcast shop uses special materials, but it is unwilling to disclose them in order to protect trade secrets.
