How do u think of jersey quality

Why have been increasingly people searching through Chinese sites like AliExpress. The reason is nothing but the low price with reasonable quality. There are countless factories in the Guangzhou and Yiwu. Well, generally speaking, replica jerseys, t-shirts, shoes and watch which are from Guangzhou have higher quality than counterparts from Yiwu.

Take Air Max 90 shoes as example, the material , design, working, procedure and QC are the same as the official. These replicas use super fiber which is high tenacious and can breath freely. Lining material is mesh, insole material is EVA, upper material is PU plus mesh, out sole use PU, too.

Ok, questions here. How do you think of these two different replicas come from Guangzhou and Yiwu.  For more, how do u think of different quality and price range from replicas.
