This is a "tasteful" video... The location where Xiaoxin is located is an enterobacteria bank in Beijing, and many people call it "poo bank".

What does the enterobacteria bank do?

Why would anyone call it a "poo bank"?

How does it work and what is it useful for?

Xiaoxin will show you the truth!
