To access Instagram and other blocked services and bypass the Great Firewall of China it is very important you get a reliable Chinese VPN service, I have tried many VPN services in China, because I had to access many foreign websites for my research project etc. so my personal experience is what gave me a lot of knowledge and the most important thing I learned is NO FREE VPN WORKS in CHINA, which is the worst thing to know, because I had to spend some money to get the stable and quick access in China. Some Top Chinese VPNs are; ExpressVPN NordVPN
No, sadly all the foreign app and sites are blocked in China so does Instagram. But many people want to use Instagramt in China but sadly it is blocked by the Chinese Government. But you can use Instagram in China by using a Reliable VPN service in China.
The only reliable way to access it is a VPN with;
Dedicated Android and iPhone apps
Servers near China
Highly Secure Encryption
Must offer Fast Speed
