I think part of the problem here may be that many Taiwanese women are deeply invested in the idea of marriage as an institution in which the man takes care of the woman emotionally and financially or at least keeps up an semblance of that being the case. Talking about finances could challenge that ideal of marriage.
Quite a few people from other places see marriage increasingly as a partnership. In the partnership view, it is very important to have full disclosure about important issues like finances.
I suspect these two views are coming into conflict. Or she may have debt that she doesn't want to discuss.
I'd be concerned about whether she is going to get an academic job. In most fields, only very ambitious and aggressive people get those jobs. They don't fall in your lap. What if she can't get an academic job and stops working after she gets married? How will you feel then?
If you really love her, I think you won't care even though it may lead to financial problems later.
