Tails cannot use tor to protect privacy in areas subject to strict censorship such as China and North Korea
In areas with extremely strict censorship, such as China and North Korea, GFWs have been set up, making the tor network impossible to connect at all, and people who need to protect themselves cannot use the browser.
You can’t use tor on Windows, macOS and other systems, but you can download and configure the front VPN to connect elsewhere, but tails can’t access the website without connecting to tor, so you can’t download VPN, and without VPN, you can’t I can't access the website when connected to tor.
I haven't been able to find a solution for the time being, which also makes my tails version stay at 5.7(There is no second U disk for the time being).
Regardless of whether this issue is resolved, thanks to all the developers who answered this question!
