Since you mentioned the eight-character problem, it also shows that you or your family still attach great importance to this problem.
The use of eight characters is still very common in China. It should be said that sometimes it seems reasonable, but most of it may be just people's subjective views.
I think besides this subjective view, you should pay more attention to some objective things. For example, this object's personality, personality, appearance, family background, knowledge, specialties, whether your own characteristics are appropriate, and whether two people can live together in the future is more important.
Of course, if you violate the eight characters, it is likely that your parents who are superstitious about this tradition will strongly oppose it. But I just hope you can think about it more objectively.
I hope I can help you, O(∩_∩)O~
