1, conflicts in life. If two people don't get along, there will always be contradictions in life. This conflict is difficult to ease, because these two people have different lifestyles and it is difficult to stand on the same line. Therefore, the main problem of disharmony is that the contradiction in life has not been effectively relieved.

2, personality disagreement. The personality between husband and wife is the most prone to friction. That's because two people didn't get enough understanding before. When couples don't understand, it is likely to cause various problems. This problem is caused by the friction of personality. This kind of friction will also make two people's marriage unhappy.

3. Deal with the differences of things. Two people will have different views when they look at a thing from different angles. When two people hold their own opinions and neither side bows, then there must be something wrong between them. Treating things in different ways will also make you clamor for a small thing to happen. If this is always the case, you will be too sad and happy.
