LOL, yeah, I don't see Zhao Xinci having much patience for lit or poetry. But I do see Zhao Yunlan learning that sort of thing just because he can, TBH. Not a lot, but I feel like he'd know the common classics. Like, he took that one mandatory Lit class and he aced it! He seems the kind to think that you never know what's gonna come in handy, and sometimes you need to pull a fancy quote out to impress the people who are giving money to your department. But it's definitely not his secret hobby or anything. :-)
