Moral of story:
Don't buy kebabs from shady places
Apparently, those cheap kebabs are made in a factory and frozen
when demand is really high(especially in the summer) lamb prices will go up
Therefore, some smaller kebab factories in north eastern china would buy ferrets from ferret farms(who only need the ferret pelt) and make them into kebabs and sell them as lamb kebabs
Good thing that I've never eaten a kebab from a street side vendor
The dishonesty in the food industry in china scares me
good thing I moved away from china last year
