Sending things is an old activity. For example, when Taiwan Water Master Energy Living Water Machine just opened the Living Water Health Experience Hall in Chinese mainland, it did send a crystal cup, but it was later dropped. I think it has nothing to do with harming the interests of consumers. After all, things are extra gifts, just like many merchants in Taobao sometimes do activities to send small gifts from time to time, but there is nothing to say if they are not in a hurry.
