It really depends..
you need to have the Official ranks in chinese from SAF.
you cannot just take a PRC or ROC army rank and assume its
equivalent, this is especially when you are talking about
non-commissioned ranks.
in most cases, commission ranks would be equivalent.
The problem comes to senior non-com ranks because the jobs being
done by the rank varies.
e.g. Master Sergeant in SAF is usually a CSM or a technical
specialist.
But in ROC, Master Sergeant is usually an RSM.
This is why our 1WO and 2WO who goes ROC for exercise usually get
"demoted"
to senior sergeants.
Same goes to 1st, 2nd & 3rd sergeant ranks, these are new ranks
to make SAF pay scheme more flexible. but they depart from the
traditional structure.
