In any case, I am going with the theory that Carrier 12 to 15 is South China Seas Hainan assignment, and Carrier 16 to 19 is North Seas Qingdao assignment.
The moment the 002 was ordered to head down south, is why and when she removed her original 17 number, resulting in crews hurriedly repainting over the number they painted on the hull.
I suspect they were originally planning to deploy 002 with the North Seas Fleet and were already putting on the "17" number. Then suddenly the higher ups called, probably because of Xi Jing Ping or the Politburo, to have a more assertive stance on the South China Sea, where the USS Ronald Reagan has been prowling around lately. The higher ups wanted the carrier to be moved down south instead. So they erased the "17" number, cancelled her Qingdao commissioning ceremony, had her pick up her complement and dashed through the Taiwan Straits for Hainan.
002's sudden relocation from its original Qingdao assignment to Hainan meant she would trade her previously assigned North Sea pennant in exchange for a South China Seas pennant.
Only the Orangeman would make such decision, CMC is not a one man show, they planed in long term of 10 to 30 years, daily or weekly affairs are irrelevant.
