The Chinese folks are very much into 'saving face'.. they will do ANYTHING to prevent being 'shamed' especially on a high profile project such as this which has not just military but political implications as well.
You can bet your last dime they will do everything humanly possible to make sure all their t's are crossed and i's dotted.
It's good for them but bad for laymen like us... they're taking it very slow and easy.. I mean heck! she sat there rusted out for almost 10 years before the PLAN turned her into what she was destined to be. Unless China intends to engage in some major naval and air engagement i'm unaware of sometime soon, a few months more of waiting and testing is nothing in the grand scheme of things.
