# Popular questions ## Basic questions ### What is the ZGC VPN? Recently, we raised the topic of Chinese censorship. We told you about free and paid VPNs\*, but the article had to be removed. We tested all the paid VPNs we could find and concluded that only two of them work normally in China, at a price of around $100, which forces us to run to the free ones, which occasionally don't work in the evening and leak your data to interested parties. In the end, **in 2018 we created our own high-speed VPN** (after several failed tests) and it worked! Now our VPN is no slower than the one that costs $100/year! \*VPN – a technology that will allow access to forbidden sites (in our case). ## ZGC VPN subscription ### Subscription is free?
