It's strange that your definition of China's "normal" displacement requires a standard displacement which you claim China doesn't use, which I find hilarious. As a Chinese that likes to co-opt Western terms and add "Chinese characteristics" to them, you should know all about co-opting Western definitions.
Not my definition, pop3's, which is also the PLAN's definition.
By not "using" standard displacement, I mean they never give their vessels' displacements in that measurement, only normal. It doesn't mean they don't have that definition in their vocabulary. Also, pop3 didn't define "normal displacement" such that it needs "standard displacement", he defined every type of displacement categorisation in terms of the ship's status and load. This is the complete synopsis:
Empty: Complete installation of ship-borne systems and nothing else. No consumables, no people, nothing except the stuff that's bolted down.
Standard: Everything installed plus all consumables and crew except for fuel and water. Munitions, food, etc. are included.
Normal: Everything installed plus all consumables and crew, and 50% fuel and water.
Full: Everything installed plus all consumables, crew, and fuel + water.
Max: Don't fill more than this or the ship sinks.
Also, this is what I said:
China uses whatever's suitable to her needs including a lot of foreign ideas. Some needs are better served by her own methods like PLAN-specific definition of "normal displacement."
