If there are a lot of analytical products, first of all, in today's era when Taobao is prevalent in cracking down on counterfeit goods, Taobao also has counterfeit goods, while there are many products. At present, the development model of many products is in the initial development period of the platform, mainly driven by the way of changing traffic at low prices. In other words, Pinduoduo merchants are basically doing small businesses that generally cannot enter Taobao, and the threshold will be much lower than Taobao. Moreover, the platform's supervision of counterfeit goods is weaker than Taobao's, and the conventional low-price strategy is low price = low quality. Although in many cases, low price is not equal to low quality, in related brands and markets, low price is equal to low quality. And Adi and Nike, which have more products than 100 -200, have so many stocks that they haven't broken the code yet. I think we can carefully consider the authenticity of this product.
