The group a person belongs to can influence a person. Because of the same uprightness, Lian Po and Lin Xiangru eventually became close friends; because of the same talent and patriotism, Li Bai and Du Fu can also maintain their friendship forever; Jia Baoyu never looks down on a rough man like Xue Pan, but always has a "special liking" for men like Jiang Yuhan and Liu Xianglian... It is impossible to get together without common interests and hobbies. Friends can be said to be the reflection of different aspects of a person's personality to a certain extent. People have multiple personalities. Due to limited ability or external conditions, they will consciously hide many aspects, but they will pin these aspects on others, often friends. Therefore, if you want to really understand a person, it is a good way to understand his friends, especially friends with whom he has a good relationship.
