So you want your app/website to work in China

The most technically correct way to be in compliance with the Chinese government’s data protection laws is to have a separate Chinese version of your app/website and run a separate version of your infrastructure in China. If you host your main infrastructure in a Chinese region then you’ll be in compliance with China’s data protection laws, while still being able to serve requests outside of China via the proxied connection. If you’re hosting your infrastructure on Alicloud or Tencent cloud in China, you can accelerate requests to your infrastructure globally using their acceleration services.
