Interesting seem like China's nuclear submarine bases are all underground tunnel. In WWII the allied bomb out the Krieg Marine sub bases and none of them are destroyed.
I think we already know that China has commissioned 4 Jin class sub and 2 are outfitting. so there is no surprise if they now commission the 2 newly built sub. the image below is from Feb 2019 when they are outfitting the sub
The SSBN Fleet
China currently operates four Jin-class (Type 094) SSBNs (nuclear-powered ballistic missile submarines) with two more fitting out. The four operational SSBNs are all based at the Longpo Naval Base on Hainan Island. The information about the fifth and sixth hulls is new and expands . Once completed, this force will be capable of carrying up to 72 JL-2 SLBMs with as many warheads, 24 more than the four operational can currently carry.

The Pentagon report says the four operational SSBNs “represent China’s first credible, sea-based nuclear deterrent,” although the report doesn’t say if the submarines are armed with missiles under normal circumstances, if the warheads for those missiles are installed, or if the submarines sail on deterrent patrols.
The six Jin-class SSBNs will be followed by a next-generation SSBN known as Type 096, which DOD projects might begin construction in the early-2020s. The new SSBN class will carry the follow-on JL-3 SLBM but China will probably operate the two types concurrently.
Chinese Navy Submarines Are Protected By Underground Tunnels

H I SUTTON
China is a maritime nation with over 9,000 miles of coastline, dotted with ports. Compared to most other countries, it has a large number of naval bases. By dispersing its forces across many bases the Chinese Navy, formally known as the PLAN (People’s Liberation Army Navy), is protecting them against surprise attack. But some of it bases go further, offering underground tunnels to protect key warships and submarines.
In the age of precision strike cruise missiles and bunker buster bombs, tunnels may seem an outdated idea. But they still provide cover against some air attack and, perhaps more importantly, prying eyes. And they can also protect against nuclear attack, provided it is not a direct hit.
China’s tend to be built directly into rocky outcrops which may provide many feet of overhead protection. The entrance is usually facing inland (but with water access) so that it is harder to hit from offshore.
The best known of these tunnels are two which protect the strategic submarine force. One built at (36° 6’20.76″N, 120°35’2.39″E) near Qingdao provides a hiding place for ballistic missile submarines based there.
And more recently one has been built at Yulin (18°12’8.97″N, 109°41’39.34″E). This is where a around 12 years ago. Yulin allows Chinese submarines (and aircraft carriers) easy access to the South China Sea, an important operating area.
Some other PLAN bases also have tunnels which are less well known. The submarine base on Xiachuan Dao has a small tunnel just inside the harbor wall (21°35’45.08″N, 112°33’5.14″E). And a shipyard where large warships and submarines are repaired, near the submarine base at Xiangshan, also has a tunnel (29°31’41.09″N, 121°41’16.98″E).
There are other tunnels which are physically removed from any naval bases. These may provide more dispersed protection, although it is also possible that some are not Navy related. For example there is quite a large tunnel in a mountain on an island south of Shipuzhen (29°11’2.75″N, 121°56’35.68″E). There is a missile boat squadron nearby, but the tunnel appears separate from any PLAN naval base. Other less obvious tunnels include some near Daishan (30°15’40.61″N, 122°19’1.43″E), and along the coast from of Yalin (18°15’42.67″N, 109°43’41.13″E).
China’s tunnels are an interesting difference from U.S. Navy doctrine. They may provide some degree of protection against an unexpected attack. And they likely increase the survival of PLAN submarines in longer wars.
The PLAN is not alone in valuing the defensive strength of rock. The Swedish Navy recently announced that it would reopen its Cold War super-base at Muskö outside Stockholm. That site can house several submarines or warships and has maintenance facilities. Other countries which appear to have submarine tunnels include Taiwan, North Korea .
