First, people with hobbies tend to be more involved. First of all, in the eyes of literati, if a person has his own hobbies, he will focus more on what he likes and have his own ideas and unique opinions. At the same time, he will be more concerned about and support people or things around him. For such people, scholars will prefer to communicate with them and think that such people are worthy of making friends.
Second, hobbies can reflect a person's cultivation. Secondly, different hobbies can also reflect the cultivation of different people. For example, some literati like to recite poems and paint pictures. It can be said that this person is rich in poetry and calligraphy. But if this person's hobbies belong to neither fish nor fowl, then a knowledgeable reader can stay away from him according to his hobbies and not associate with such people. In addition, people without hobbies are particularly terrible, because they can't judge this person's preferences, and they can't know what kind of person this person is.
Third, personal preference is the way of communication. Finally, hobbies are also the way of communication between literati. For these people who only read books on weekdays, if a person has the same hobbies as them, then this is a topic of communication, which can help them have a broad spiritual exchange about their hobbies. But if they don't know other people's hobbies, they will lose the best chance to communicate with others and even be labeled as heartless. So in ancient times, it was a good thing to have a hobby, but it was not a bad thing to really have no hobby. It was just that people with hobbies knew few friends.
