I don't know if they're called Wolf Berries in the States or not. But that's what we call them here (in English). Anyway, they are a huge export out of China and the new fad health food around the world. I don't know why they're healthy but they are. Companies are doing something like making juices out of them for athletes or something. They're expensive everywhere but here. Here...they're everywhere and come in huge quantities as you can see! I personally don't like the taste of them, but others do. Go to the store and buy some if you dare!
