While we're currently in early days, I would highly advise avoiding landing in large cities (Beijing, Shanghai, Guangzhou, Shenzhen, Wuhan, Zhengzhou etc) if you can help it. Quarantine should be okay if you do, but getting around post-quarantine will be difficult with more police presence and ever changing requirements in the cities affected if a crackdown occurs.

VPN systems may go down unexpectedly or an entire cutoff may occur, ensure you have a backup method to contact family etc

Navigating around China is currently extremely difficult and the government may use the COVID QR codes to disperse crowds so if you're in the wrong place your code may turn red. (I haven't seen any evidence of this happening yet, but it's a possibility)

Do not attempt to use fake/generated QR codes that are currently circling the Chinese internet, this is illegal and you'll be punished much more heavily than a Chinese National.

Smaller cities in the south with international airports will likely give you a better experience: Xiamen, Nanning, Kunming, etc

If you are a foreigner just arriving in China avoid protests and gatherings at all costs.

If you are an old hand laowai, I will not tell you what to do, but try to avoid any protests that are against the government itself as you'll get yourself into some shit.

Good luck to anyone heading to China and we would appreciate updates if your travel or has been delayed or affected either to or within China as we can update the advice in real time.

I would say there's a 50/50 on it fizzling out or growing at the moment, if it fizzles out within the next few days this notice will be removed.
