What if... I'd cut off all connections to China on my home network? (alien.top)

I'm just curious, what if I'd use my pi-hole to block all connections from/to China on my home network. I have a good bit of automation in place, but mostly western solutions, yet still I wouldn't be surprised if they called China. Have any of you tried this kind of experiment? Is it even possible to block? What gone down?

Pihole only does domain blocking. Let’s say spookydomain[.]cn resolves to 1.2.3.4. You could block spookydomain[.]cn through pihole but nothing would stop a computer from directly interacting via IP address or from the Chinese to buy spookydomain[.]org and evade the block. To do a true country block, you’d need to do it at the firewall and have up to date geoip data.
