Scan passport and mobile bp at the machine, then the gate opened, pass thru the gate, it takes a photo of you, thru. (similar to hk transit)
Security, they werent expecting people to come, so took them 2 or 3 mins to get eady
The security staff used his webcam to capture a photo of me.
Security check, as mentioned by others, powerbank must be separated
It seems all persons pass thru the metal detector will beep,pad down.
Walked to gate (signs arent clear)
Asked gate staff if I can change. (must enter and exit China, but time is not enough)

Now at PEK waiting for CX393.

I booked CX332, CX393

I used passport throughout all formalities.
PEK same plane turnaround is possible if you have mobile boarding pass, but is it advisable? Up to you.
Btw, from PEK gate staff, I have heard there are 5 broken J seats for the Aria Suite.
