Well, I’d say that the Chinese would have figured that in the time that it takes for a situation to escalate enough to lead to a missile strike into the cave, they can get all of their subs out of there, and into the sea.

More likely, they have a "Red" crew/"Blue" crew rotation with about half the fleet at sea and on station at any given time. If their subs are nuclear powered they can loiter submerged for at least six months.

The 'fleet' currently consists of a single boat, and all indications are it has a single crew. Russia didn't adopt the dual crew concept for their ballistic missile submarines and it's doubtful that China will either.
