In ancient times, friends were made friends through literature, and activities such as outings and autumn outings were held to enhance the relationship between friends. In this process, only those with the same or similar intelligence, talents, or political opinions could become friends. As the saying goes, Taoism Different people do not seek each other. The ancients had very few friends, and the pursuit of close friends was the criterion for making friends. Of course, there was no shortage of confidantes.
