You can't test whether a website is blocked in mainland China by opening it from home — blocked sites generally load fine from outside the country, so that test tells you nothing.
A dedicated 'is it blocked in China' checker site, used before you travel, is the practical way to actually find out, since the list of blocked sites is commonly reported to shift over time.
Check your must-have sites with a checker tool ahead of time, and set up and test a VPN regardless.
Why you can't just try it yourself first
The Great Firewall filters traffic based on where the request is coming from — a site blocked for connections originating in mainland China is commonly reported to load completely normally from your home country. That means opening the site from home, even the night before your flight, doesn't tell you whether it'll work once you land.
Several free 'website blocked in China' checker tools exist that simulate a connection from inside mainland China and report whether a given URL loads — these are the commonly used way travelers check ahead of time.
How to actually check
Use a China-firewall checker site
Search for a 'website blocked in China checker' tool, enter the URL you care about, and it will report whether that site is commonly reachable from inside mainland China — do this before you fly, not after you land.
Have a VPN ready regardless
Since blocked-site lists are commonly reported to shift, and a checker tool is a snapshot rather than a guarantee, setting up and testing a VPN before you fly covers you even if something changes between your check and your trip.

Before you fly
Make a short list of the specific websites or apps that matter for your trip — work tools, banking, communication — rather than trying to check everything.
Use a China-firewall checker site to test each URL on your list, and note which ones come back as commonly blocked.
Install and test a VPN before you fly, so anything not on your list — or that changes later — is still covered.
Real mistakes travelers make
Testing a site from home and assuming that's the answer
Testing a site from home — even the night before your flight — doesn't tell you anything about whether it'll work once you land.
Workaround: Use a dedicated China-firewall checker tool instead, which simulates the connection from inside mainland China.
Commonly reported
Treating a checker result as permanent
What's blocked is commonly reported to shift over time, so a check done weeks before your trip may not reflect the situation on arrival.
Workaround: Recheck close to your travel date for anything important, and have a VPN ready regardless as a catch-all.
Frequently asked questions
Can I just try opening a website myself to see if it's blocked in China?
Not reliably — the Great Firewall filters based on where your connection originates, so a site blocked for mainland-China visitors often loads fine from your home country. Testing it before you fly doesn't tell you what'll happen once you land.
What categories of sites are commonly blocked in China?
Google services, Meta apps (Facebook, Instagram, WhatsApp), and several other foreign messaging and social apps are widely reported blocked as categories. Some foreign news sites are reported as inconsistent. Most other ordinary websites are commonly reported to load normally.
Does a blocked-site checker replace needing a VPN?
Not entirely — a checker tells you the current situation, but blocked-site lists are commonly reported to shift over time. Having a VPN set up and tested before you fly covers you even if something changes.
