He had a real product! Spent about US$20K (¥140K) on raw materials and whatnot. He told me all the details, but frankly, my Chinese is NOT that fluent and he was so excited and speaking so fast, I didn't have the heart to interrupt him to make him repeat it. Basically, they automated the assembly of some other products into 4 completely different finished products. He came up with the idea when he heard and read how AMZN screwed his previous clients. He and his wife did sourcing for foreign buyers. Some of these foreign buyers outsourced his services to find them a product, purchase it, pack it, and ship it to their FBA account.
He had an army of "buyers" all over the world, probably Chinese, buying products off AMZN and ALiExpress etc etc. I know he referred to them as Wumao!
Wumao ¥½ = US$0.07
