TECH: Don't Need It, Leave It
The Chinese government has publicly declared that it regularly monitors private email traffic and Internet browsing.
Remove personal and sensitive information from your devices before you travel. If you must bring laptops or cell phones, keep them in your possession at all times.
Do not accept free thumb drives, open suspicious links, or connect to unsecured wireless networks. Protect your electronics with up-to-date anti-virus software.
Understand that many news and social media websites (e.g., Facebook, Gmail, Twitter, YouTube, etc.) are blocked in China, and plan accordingly.
