In daily life, we have the following two ways of calling good friends:

1. Zhiyin.

2. Confidant.

If the relationship between two people can be called "bosom friends" or "bosom friends", it means that the relationship between the two people is a true good friend relationship.

However, although "bosom friend" and "bosom friend" have similar meanings, there are also many differences between the two concepts.

Specifically, the differences between "bosom friend" and "bosom friend" are as follows:

1. Bosom friend emphasizes objectivity.

Zhiyin emphasizes that two people have the same or similar views in certain fields. Because they know the same, they appreciate each other and become bosom friends.

For example, if one person plays the piano well, another person can discover his talent in this field, and then they can become close friends.

2. Confidant emphasizes subjectivity.

Confidant refers to the state of mutual understanding between two people. ...Rather, this kind of understanding is still a very deep understanding, understanding what the other person is thinking, being able to talk to each other, and communicating candidly with each other. Only in this kind of relationship can we become close friends.

3. Bosom friends refer to people who have similar interests.

Zhiyin analyzes problems more from the perspective of professional skills and interests. ...Two people who become bosom friends must have the same or similar views and opinions in certain professional fields and appreciate each other.

4. Bosom friend refers to the mutual affection.

The relationship between close friends focuses on mutual understanding at the emotional level and a heart-to-heart relationship. ...Between close friends, one can express one's views and opinions candidly, and the other can candidly accept the other's views. Only when the two have reached mutual understanding psychologically can such a relationship be called a close friend.

The above is the difference between a close friend and a confidant. ...Of course, these differences are relatively minor. In daily life, two people are described as close friends. They can be called bosom friends or bosom friends. The meanings are basically the same.
