This Yang Wangchuan is no ordinary person, you can't just describe him as having a bad temper, but rather...
Very rigid, conservative, even somewhat stubborn and inflexible, a particularly obstinate person.
Colluding together?
Complicit in wrongdoing?
Upon hearing such accusations, everyone felt Yu Zhen's behavior was utterly ridiculous.
"She claims Mr. Yang and Tang Wan conspired together, this could be the biggest joke of the century. Who doesn't know Mr. Yang's temperament? You couldn't make him do such a thing even if you put a knife to his throat!"
"And he traveled all the way from Nanjiang, how capable is Tang Wan?"
"It's good enough to have him come here, let alone have him falsify things in public? Yu Zhen must be crazy; no one would cover up plagiarism, and certainly not Yang Wangchuan."
"She's acting like a cornered dog, snapping at Tang Wan the first chance she gets, is she out of her mind."
