Actually, I don't think this is appropriate. Many lovers who love each other are blocked by their parents because of their incompatible personalities. However, couples with a combination of eight characters may not all have a happy marriage, and there are still cases of divorce. So don't turn these eight characters into a standard to judge whether a marriage is happy or not.
The contradiction between husband and wife is inevitable, and the most important thing is whether it can be handled in time. If everyone doesn't want to solve the problem, it will easily lead to intensified contradictions. Husband and wife should be tolerant of each other, look at the problem from each other's point of view, and reduce the friction between the two sides.
