What's the difference between Sybil Mall and Jingle Express Medicine?

Dangdang Express Medicine is a medical and health Internet product based on o2o, and it is a third-party information display platform to assist pharmacies to provide convenience services. There is also Xibairui Mall. To be honest, I have checked it for a long time and saw many articles about it, but none of them can simply tell me what it is, and forcefully pull together blockchain health big data. The question is whether I have finished reading it or not. So my last feeling is that this thing is very unreliable.
