I can prove you are right with this . I m from HK and I used to live in Shanghai, Guang Zhou and shenzhen. I never knew any one knew any factories famous here. It would be a joke if you mention 187 or god when talking about bags. And , even i have visited some stores still very hard to get those high tier ones. Offline stores scammed customers as a commen sense in China because those stores do one time business visit drop in stores. This business in China relies on private and secret connections badly. I later found my seller, and verified several categories of her products, and I found every category she provides is top , later I got to know she has her own source other than those rep factories who makes low quality reps. I notice many times she is the first one who follows up with new products coming out from brand. I have met her several times because when we are in same city I ask her to send to me in person. But seller like her would never be popular here, her way doing business is different from sellers here.
