Dude. Its not a matter of prefference. YJ83 is designation for the missile in service with the PLA and C802A is its export designation as allocated by the MANUFACTURER.
Its not up to opinion, C803 is a non-existant designation written in error by western defense analysts.
Read through this ezhaustive piece.

If you still insist on this misleading C803 nonsense, I'm starting to understand no_smoking's disdain for you.
Try fact-checking your posts mate.
The manufacturer says the proper name for the J-31 is the FC-31. Does anyone else besides the Chinese government or manufacturer call it the FC-31? Not really.
The navalized DF-31 ICBM is named JL-2 SLBM.
The navalized DF-41 ICBM should be named JL-3 SLBM. Yet, the Chinese government or manufacturer calls it the JL-2A.
The original cigar-shaped-nose Chinese submarine was named Type 039.
Yet, the tear-drop-shape Song class diesel-electric submarine was named Type 039A. Many people acknowledge the old original Type 039 is obsolete and just call the Song as the Type 039.
The Yuan-class diesel-electric submarine has AIP and can stay underwater for 3 to 6 weeks. Yet, the Chinese government or manufacturer calls it the Type 039B. No one in the West is going to memorize the A, B, and C designations for Chinese submarines. Thus, we call it the Type 041 Yuan-class submarine with AIP.
I don't have a problem with your preference to call it by the technically-correct Chinese government designation. However, most people use the common designations because it makes more sense and it is easier to distinguish between the Chinese weapon systems.

Off-topic: Do you really think that I care what No_Smoking or anyone else really thinks about me? This is a hobby. Give me a break.
I think only two people like me. Grey Boy 2 and possibly Chinese Tiger 1986. Everybody else doesn't seem to like me. I've never been popular for some reason.
Anyway, since I'm probably the only Taiwanese-American of ethnic Chinese descent armchair-general on the Internet, I don't expect people to like me.
