For an ideal sibling relationship, the ideal age difference is 3-6 years old. But in real life, there are years to decades of differences. As for the love between brother and sister, it has existed in China since ancient times. Up to now, there are also many star groups in our country.

According to a survey conducted by the Social Science Data Research Center, women are 3-4 years older than men in marriage and have the highest happiness index. This actually tells us a truth: the psychological age of men and women with this age difference is basically matched.

How to know whether two people in a brother-sister relationship are suitable for marriage, I think there are the following points:

First, the communication is relatively smooth, and the speech is basically on one channel;

Second, hobbies are basically the same. Men like to stay up late to make friends and play games, while women like to be quiet and enterprising and can't play together.

Third, the three views are basically the same, and the views on the problem will not differ much;

Fourth, maintain independent personality and achieve mutual respect. Women are not strong and men are not overly dependent.
