As long as it is an officially certified flagship store, it is reliable. I bought this mainly in the brand flagship store in Pinduoduo, so I can rest assured. The quality of flagship store is guaranteed. YEATION has become a brand, but it needs to be known by more people. Pinduoduo is such a platform for more people to know. I just don't know if this platform can make YEATION get more users among consumers. YEATION may want to harvest users in Pinduoduo. Just like a department store selling shoes of various brands, it entered Nike Adi. The chaos in many products may highlight the reliability and sharp contrast of YEATION, just like standing out from the crowd.
