[X] Bring Zheng Fu on and go to talk to the Ministry with him along.
If you want future Qingge's to be able to say No to an offer like this because she thinks it'll make her life worse instead of better according to what she wants, and to be able to do that while expecting to not be punished enough to ruin her life for disobedience to clan interests, you need a lot more of a legal presence sticking their noses into clan affairs and dictating how they do things. And boy do people really hate that. It's a really tough nut to crack with very deep cultural roots, but a worthwhile one. In a better world no one would be able to do anything to convince Qingge to take that offer except to offer her further rewards for doing so.
The cure may well be worse than the disease here.
The root cause is that a clan simply has too much soft power for any individual component of the clan to resist effectively when it comes to matters of clan interest. There is a lot of degrees of emotional, material, and physical coercion available, even as simple as cutting off cultivation supplies or assignment to menial labor, to even limited physical punishments(as per the culture of the period, a great deal of punishments are permissible if you avoid causing permanent damage...and for a cultivator that allows for a great deal of inventive circumvention) and solitary confinement.
This further intersects with clan secrets and Ways, which are a strategic military element of a cultivating feudal society. You don't get whistleblowers - even if they disagreed with a specific decision, actually going to an outsider on the matter invites the ruination of the clan, so the best bet is to cultivate high enough to have an executive vote on decisions, something made harder by clan internal politics.
So how do you fix this then?
Theres many approaches but it boils down to 3 solutions:
-Abolish the clan and feudal system as a fundamental building block of society, replace it with something else to turn resources into cultivators. Of course, the basic workings of cultivation means you're still permanently concentrating a lot of power into a small number of individuals so consider whether a CEO, Living God or President-for-life is going to do any better than a clan head...and of course clan-like structures will still form anyway because you aren't going to stop people from having personal relationships with their relatives, and a 300 year old patriarch/matriarch is more or less going to be a heavy fixture just by weight of connections.
-Greatly strengthen the central state's ability to interfere in family matters. Note that central state is going to be a lot more enthusiastic about imperialism than individual quality of life, and consider that the main limiting factor is that it can't force its component clans to do anything unless it genuinely appeals to a common interest. It is entirely possible that forced marriages for clan alliances and clan eugenics simply get replaced with forced marriages for state alliances and state eugenics.
-Somehow force greater empathy and communication between the decisionmakers of any group and the individuals that have to bear the costs. Would probably take an Ascension and considerable amounts of worship and support to actually make happen on anything more than one clan scale.
TLDR - What drives this is power dynamics in the end, once the people that call the shots are too distant from the people that actually carry it out it can be considerably difficult to care about the details.
Damn, are we really going to need to intervene personally to see justice done about this? By which I mean the Liu young master dead, the Liu's precious family reputation dragged into the gutter where it belongs, and the He clan never having power over anyone ever again.
Even if we intervened personally 'justice' would not be done in all likelihood short of personally assassinating him and then probably see our family caught in a blood feud they can't win.
They could be punished, but what happened to Qingge is just a misdemeanor charge.
What
else they're doing in Tonghou sounds like grand felonies though, so that'd be nice to look forward to when the audit gets there. But its not a quick process, and its quite likely that the direct offender isn't actually important enough to get smashed for it.
