Universal sockets and euro plugs: what about grounding?

Question

Standardization

Hello everyone, I have a question about the standardization of sockets. I want to install universal sockets at home. But I see that the "ground" contact in our euro plugs does not come into contact with anything in these sockets. How to be? Is grounding not used at all in China (just the USSR in the 70s)? Or does the third contact just look different? And one more question about the sockets. Well, they also have their own standard, how are they attached to the GKL?

question about sockets. Well, they also have their own standard, how are they attached to the GKL?

For mounting in the GKL, there are special sockets. They have screws with "legs" - spacers on the sides.
In stores selling electrical installation products, ask the seller: sockets for gypsum boards.
Just do not take socket boxes with plastic "paws" - spacers. Look for metal, for example, here's how to follow the link:
And when installing, do not pinch the screws of these legs: the drywall will collapse and the socket will hang out.
