Whether PLAN is serious about firefighting can be easily confirmed by one thing as far as I'm concern.
Do they teach and practice firefighting even as far back as bootcamp? Is so good, if not then Xavier is right. PLAN appears to not take firefighting seriously then which would be a cardinal sin in a modern navy!
Any Navy which puts firefighting in the back burner no pun intended can't be a world class navy.
Firefighting is one of the most important component of seamanship.
Every recruit in USN RTC has over 40 hours of firefighting training just in bootcamp alone.

Talking to someone who knows a bit more about this stuff, there are a few observations.

In terms of watertight doors and watertight bulkheads, they wouldn't be present on the levels in which the standard PLAN ship tour would go (i.e. through the superstructure, at that level), and instead are present at the waterline level and above, but not as high as the main structure level. If that level is at risk of flooding then your ship is probably done anyway.
I'm not sure if US or other ships have watertight doors at the super structure level as well, or if Xavier has had more liberal tours of other non-PLAN ships (likely, given his past write ups).

The corridor in which the trip goes through is probably one of the side main damage control corridors that PLAN ships have (at least one on each side), designed to be relatively smooth and unobtrusive. Damage control stations are interspersed along the corridors inside, to allow teams to get to where they need to be. And of course we've also seen enough pictures and videos of fire extinguishers being present in the ship's various locations. I'm not sure if they deliberately don't have any fire extinguishers along the DC corridors because of the assumption that DC stations are so close on hand, or if they just removed them for the tour. Anecdotally I remember years ago when I was on an 054A for a tour, it took a similar route that was only on the side corridor which would have been the DC corridor, and it didn’t go deeper inside the ship in any direction.


That isn't to say there aren't likely some differences in DC philosophy between PLAN ships and that of other navies, but if my guess is right, this is a very flawed sample to make the conclusion of "they don't have watertight doors/bulkheads, or fire fighting/DC equipment".

Even the torpedo and RHIB davit aspect was a little confusing to me, because while there may be no door separating them, if the concern is over secondary explosions or fire spreading due to damage, the kind of damage you'd be suffering is likely to be of greater concern. Not to mention on other ships of the world where the torpedo launchers are exposed, right in front of the RHIB (exposed as well) and also adjacent to the VLS.

I found these Chinese papers "The application and development of watertight door on foreign naval warships" and "Discussion on the Selection of Marine Watertight Door" which is from Naval Armament Department of PLA.

Conclusion -
从国外海军舰船水密门应用和发展可以看出,美国海军在水密门的设计、试验、使用和维护等方面均有较为系统的规范标准。针对我国舰船水密门关闭不严、承载能力较弱、缺乏抗冲击指标要求、规格类型多、耐腐蚀能力差、难于维护保养、标准规范体系不完善等问题,为了进一步规范水密门设计选型,改进水密门的性能,建议开展必要的系统性研究工作,深入分析、解读国内外规范要求的内涵,广泛听取使用部队的意见,从提高承载能力、增强抗冲击性能、提升标准化水平、减轻重量、提高耐腐蚀能力等方面入手,修改完善我国规范中有关舰船用门的设计选型方法和要求,以进一步提高我国舰艇的抗损能力。

From the application and development of watertight doors of foreign naval ships, it can be seen that the US Navy has relatively systematic norms and standards in the design, test, use and maintenance of watertight doors. In order to further standardize the design and selection of watertight doors, the watertight doors of Chinese ships are not tightly closed, the carrying capacity is weak, the lack of impact resistance index requirements, many types of specifications, poor corrosion resistance, difficult maintenance, and imperfect standard specification systems. To improve the performance of watertight doors, it is recommended to carry out necessary systematic research work, in-depth analysis and interpretation of the connotation of domestic and foreign normative requirements, and extensively listen to the opinions of user units, from improving bearing capacity, enhancing impact resistance, improving standardization level, and reducing weight, improve corrosion resistance and other aspects, modify and improve the design and selection methods and requirements of ship doors according to our country's codes, so as to further improve the damage resistance of our ships.
