The Zhengzhou metro, one which got flooded, has blast doors in, and in between stations like most metros in the Bloc.

The anger now is because despite millions spent on those blast doors, they were simply not activated. The shift chief of the metro was too afraid to stop the metro.

The same for its very powerful flood defence pumps.

Reminds me of a documentary on the flood gates at the Port of Rotterdam. They are operated automatically, humans cannot trigger them (if memory serves well). Reasoning was, that operators live nearby and might tend to close them too soon and too often. Now you have to trust the system to have a proper balance between keeping the port open and protecting communities. Up to now the Rotterdam system seems to work reasonably well so.

And nobody needs to be worried about being fired for closing them 'for nothing'.

Exactly.

Do you have a source for that please?

I don't have a source for their statement specific to the doors, but here are some videos that capture how horrific events are unfolding in China the last few days. [1] I suspect finding documented sources of mishaps will be tricky as they will likely be moderated [2] once found.
