Hi all, my spouse and I are planning a trip to china this year for vacation, in October. I was hoping to field some advice on where to go exactly, what to see, and general advice on navigating while only understanding English. What apps should I install on my phone for payment, translation, etc.

Rough plan currently is to fly into Hong Kong/stay for 1-2 days. Train to Shenzhen for 1-2 days. Train to Beijing 1-2 days. Then fly back.

Not sure exactly what we want to see, yet. For sure, the Great Wall. Also want to take a super fast train to Beijing.

Happy to hear all your thoughts, thanks!
