What Is the Great Firewall (GFW)?
China’s Great Firewall (GFW) is, in simple terms, a massive digital barrier maintained by the Chinese government.
Services like Google, LINE, and Instagram — used freely in many countries — are inaccessible inside China because the GFW actively monitors and blocks internet traffic.
The GFW originated from the “Golden Shield Project”, launched by the Chinese government in 1998. Its primary objectives are:
- Information control — preventing the spread of content deemed unfavorable to the government
- Protection of domestic tech companies — shielding platforms like Baidu, WeChat, and Alibaba from foreign competition
- National security — filtering content considered harmful from a security standpoint
The scale of the system is staggering. According to a 2021 study reported by Gigazine, approximately 311,000 domains are continuously blocked by the GFW — a figure that represents a significant share of the global web.
How the GFW Blocks Websites: 4 Key Techniques
The GFW uses a combination of technologies to intercept and block internet traffic:
- IP Address Blocking: The most straightforward method — connections to specific server IP addresses are blocked at the network level.
- DNS Poisoning (Spoofed Responses): The GFW interferes with DNS resolution, returning false responses such as “this domain does not exist” to prevent users from reaching the intended server.
- Keyword & URL Filtering: Unencrypted traffic is scanned for prohibited keywords or URLs, and matching connections are terminated.
- DPI + SNI Filtering: The most sophisticated technique. Even in encrypted (HTTPS) connections, the GFW reads the Server Name Indication (SNI) — essentially the “destination address written on the outside of the envelope” — to identify and block specific domains.
Recommended VPNs for Use in China
At VPN Life, our editorial team regularly conducts hands-on VPN connectivity tests from inside China.
Based on those real-world results, we’ve curated a shortlist of VPNs that are especially reliable for travelers and residents in China.
For full details, see the article linked below.
Our team members are based in cities including Tianjin, Suzhou, Yuyao, and Nanchang, where they use VPNs as part of their daily work and personal routines.
In addition to these home bases, business trips to Beijing, Shanghai, Xiamen, and other major Chinese cities allow us to verify VPN stability across a range of network environments.
The table below summarizes our testing methodology.
| Testing Period | Main Test Locations | Details |
|---|---|---|
| April – September, 2024 | Tianjin, Shanghai, Suzhou, Nanchang, Ningbo, Yuyao | Test Results (Japanese) |
| October – December, 2024 | Tianjin, Shanghai, Kunshan, Suzhou, Ningbo, Yuyao | Test Results (Japanese) |
| January – March, 2025 | Beijing, Tianjin, Shanghai, Suzhou, Yuyao, Ningbo | Test Results (Japanese) |
| April – June, 2025 | Tianjin, Shanghai, Suzhou, Yuyao, Ningbo | Test Results (Japanese) |
| July – October, 2025 | Beijing, Tianjin, Shanghai, Suzhou, Yuyao, Chaozhou | Test Results (Japanese) |
| November, 2025 – February, 2026 | Tianjin, Shanghai, Suzhou, Yuyao, Guangzhou | Test Results (Japanese) |
FAQ
Is it illegal to use a VPN in China?
The Chinese government officially permits only state-approved VPNs. However, there are no confirmed reports of foreign travelers or visitors being penalized for using commercially available VPN services. That said, VPN use by individuals remains a legal gray area.
What happens if I use the internet in China without a VPN?
Without a VPN, the majority of services commonly used outside China — including Google, LINE, Instagram, and YouTube — will be inaccessible. Domestic Chinese services such as Baidu, WeChat, and Baidu Maps will work normally, but you may lose all means of contacting family, friends, or colleagues back home.
Is LINE completely unusable in China? Are there alternatives?
LINE is effectively blocked in China without a VPN. With a VPN, it works as usual.
As an alternative, WeChat (微信) is the most widely used messaging app in China. It’s a good idea to exchange WeChat contact information before your trip.
Can a site be blocked even if the checker shows “OK”?
Yes. The GFW’s restrictions are updated without prior notice, so a site that is accessible at the time you run the check may be blocked by the time you arrive in China. Restrictions tend to tighten around politically sensitive events such as the National Party Congress or national anniversaries.
We strongly recommend preparing a VPN regardless of the checker results.
Which VPN works most reliably in China?
Based on VPN Life’s testing, 12VPX and UCSS have consistently demonstrated the most stable performance. Both have a strong track record of use inside China and are trusted by many users.
On the other hand, major global providers such as NordVPN and Surfshark have been unable to connect during our tests.

Can I use the same VPN on both my phone and computer?
Yes. All of the recommended VPNs support simultaneous connections on multiple devices (smartphone, PC, tablet) under a single subscription. Be sure to install the VPN app on all your devices before departing.
