Making room for new boats.

According to East Sea Fleet's tweet,  the pair of Type054 (FFG525 and 526) are now at their new home after being transferred out of the 3rd Destroyer Flotilla.  Considering that their new home is in Ningde and they are also photoed  together with FFG 566; they are now members of the 3rd Frigate Squadron, East Sea Fleet's coastal defense unit.   .

It is a natural evolution, I suppose.
