I'm giving this a higher rating than I might based on reviewing it as a didactic example of how rescue squads operate, and as a recruiting device for volunteerism.
Though some of the marketing makes it look like a cp drama, it is in fact an ensemble cast, with the focus being on the diverse people that make up volunteer rescue squads. It’s very politically safe and I was not surprised they chose to air it during the party congress.
Surprisingly for the moralistic/didactic theme, I thought all the couples were really cute and well done, so if you want romance, there is some. The special effects and sets were realistic, and everyone’s tragic backstory was tragic. You may need tissues for this one if you’re a crier.
The point is that everyone has a role to play - yes, even Ding Ding Ding. She kinda grew on me by the end.
It wasn’t without some super cringe moments though (spoiler: the little orphan would be doubly scarred for life by their wildly inappropriate attempts to help him 'heal’) but in general was ok.

Wu Qian was really good - I’d only seen her in two things when she was much younger, and she really is a mature, talented actress. Her character was written as cold and uncompromising though, so it was hard to really like or relate to her. Luo Yunxi turned in a decent performance as a disaster survivor with MAJOR PTSD who has a laundry list of issues that he really should be working through with a therapist but...it's cdrama land so we can't do that.

Pros: acting, special effects, ensemble cast, cute dog
Cons: not enough of the cute dog, didactic and moralizing, choppy editing and weak plot that made it feel a little like 'how to survive x disaster’ instructional videos strung together rather than a coherent drama
