In conducting more research into the PLA Engineer Equipment of the PLA, I usually every now and then drop into the China Defense Blog for commentary and images and one post by (I think) 'Coatepeque' was on the numbering of the units. I could have sworn that this Thread had this information, but my searching skills are lacking so I am dropping the link. (moderators or members is this is incorrect please let me know).

Quote from the link;
LZ = Ground Central, LB = Ground North (Bei), LX = Ground West (Xi), LD = Ground South (Nan) and LD = Ground Dong. LJ= Ground xinJiang
LD21 - 71st Artillery Brigade, 71st GA reads Eastern Theater Command (LD), support brigade of the 1st Group Army, in this case, 71st Group Army is the rated 1st within the Eastern Theater Command.
LD32 - 124th Amphibious Combat Assault Brigade, 72nd GA, reads as, Eastern Theater Command, combat line brigade of the 2nd Group Army which is the 73rd GA
LD52 - 91st Amphibious Armored Assault Brigade, reads as, Eastern Theater Command, combat line brigade of the 3rd Group Army, which is the 73rd GA
My interest is in the
91st Amphibious Armored Assault Brigade b/c when it pops up in the news or press there are usually good images!
