You won't casually breach the GFW. I would treat any advice posted publicly on the internet about how to breach the GFW as probably-malicious. They are better at networking than you are.
Beware when using VPN to breach the GFW. Recently a Chinese netizen had to pay over 1 million yuan (>145K USD) for using VPN [1][2]. Before this incident, only VPN service sellers were prosecuted [3]. Beware when doing this casually.
Foreigners need to worry about the new Chinese anti-espionage law instead [1]: at least 17 Japanese nationals have been recently accused of spying in China [2], and a US citizen jailed for life [3]. The German car industry is worried [4].
The law broadens the scope beyond what it originally sought to prohibit – leaks of state secrets and intelligence – to include any “documents, data, materials, or items related to national security and interests.” [1]
