Using V2Ray to break through network blockade and access the Internet is undoubtedly the best choice at present. On the Windows platform, we have many choices, such as v2rayN and Clash; on the Mac platform, we can use ClashX, etc. But for Linux systems, we have even fewer choices. Fortunately, a very useful and highly extensible V2Ray GUI frontend on Linux is Qv2ray.

v2rayNG is a popular free and open-source application that allows users to bypass Internet censorship and access blocked websites and apps, developed by 2dust from China. It is essentially a GUI frontend for V2Ray on Android platform, using the V2Ray protocol to provide secure and private Internet access.

In order to "help" citizens of many countries bypass a series of restrictions and get in touch with Western media, the US government has provided a lot of funding to many technology companies that provide VPN services through USAGM, including three companies that establish virtual private networks - Psiphon, Lantern, and nthLink. Meanwhile, USAGM is supporting the development of a range of tools to bypass censorships, including VPNs.

The popularity of the Internet brings rich and interesting network resources, but it also brings threats to our online security and privacy. For example, advertisers monitor users' online activities through the Internet; hackers break into users' network connections; malicious attacks on harmful websites are increasingly rampant, and so on. As we all know, using anti-virus software alone is not enough to guarantee our online security now. Therefore, we also need a reliable network security software to provide comprehensive protection.

As is known to all, the serious network blockade and censorship in Mainland China (namely the GFW founded in 1998) has given rise to numerous excellent proxy software from China, including but not limited to: Freegate, UltraSurf, SoftEther VPN, GoAgent, Shadowsocks, cow, Lantern, and more. Among them, Shadowsocks (AKA: 影梭) is a free, open-source, cross-platform, encrypted, and secure small proxy project from China. It uses the SOCKS5 proxy protocol (similar to SSH tunnel), and runs very, very fast. In China and many other countries, it's widely used to break through the GFW-like Internet blockade and censorship and access the disturbed, blocked, or shielded web sites and web services around the world, such as Google, YouTube, FaceBook/Twitter, and more.
