For most people, books are an important way for them to acquire knowledge and seek ideological pillars. People who write books can not become the guides of the social era. In the people who write books and the complicated sea of classic books, very few people can really leave a deep impression in people's minds. 
The quality of the work is not so much but the essence
 for those writers who do not take profit as the main purpose and those who devote themselves to the cultivation of ambition, for those scholars who seek all kinds of subjects, a small amount of works, a lot of painstaking efforts and eternal exploration are of the same value.
