I saw this on the TV the other day, if you have google earth go to 18 12'10.47"N 109 41'41.09"E and you will see the entrance to the Chinese new
underground sub base capable of housing up to 20 subs.
If you look around the rest of this base you will see two 950 meter piers and three smaller ones would be enough to accommodate two carrier strike
groups or amphibious assault ships.

Here is a little linky if you don't have GE
