The dialogue in these chapters is absolutely razor-sharp. Let me just quote one exchange because it perfectly captures everything:
"You lost fair and square, and now you're blaming someone else—why should my sister-in-law apologize?" — Lu Zhengming, defending his sister-in-law with the fierce loyalty of someone who's already picked a side.
vs.
"I'm not going to the infirmary with you, and I'm not apologizing. Su Weiwei chose to leave, and she alone should bear the consequences. That has nothing to do with me." — Su Wanqing, ice-cold, no hesitation, no performance.
These two voices are completely distinct. Lu Zhengming is hot-blooded and direct. Su Wanqing is measured and lethal in her calmness.
But the real dialogue masterpiece is Su Weiwei. Everything she says is designed to sound selfless while being deeply manipulative. "Wanqing, I'm sorry. It's all my fault. I shouldn't have competed with you in cooking, and I shouldn't have run off during the typhoon, causing everyone to misunderstand you…" She apologizes for existing, which makes Su Wanqing look like a monster by contrast. And then she adds, "Don't worry, when Lu Yan returns, I will explain everything clearly to him. I won't let you two fight because of me." Translation: I've already told Lu Yan your side of the story, and I made sure he believes ME.
Lin Man's dialogue is equally delicious. "Comrade Lin, you can eat carelessly, but you can't speak recklessly." — Su Wanqing's response to Lin Man's gossip is perfect. It's witty, it's dismissive, and it completely shuts down Lin Man's moral posturing.
The narrative voice itself is also worth praising. It's close third person, mostly anchored to Su Wanqing's perspective, and it captures her internal calculations without ever feeling like an info-dump. We know what she's thinking, we feel what she's feeling, but the prose never stops moving.
