As foreign Cpt you will always fly P2,ie the Chinese Cpt will always be P1 ,after 1 year you can do P1 check and fly domestic with 2 f/os.
Long Haul you always have 2 Cpts 2 F/os.
As P2 you log in column “flight time as pilot” the block time in “PIC” column your time in LH seat,
You need 3000 PIC jet hours to try at CSA so assuming you are one of the 20% or so to pass and you don’t need command time its no issue, if you need command time don’t go..
