A person's speech has "taste", completely depends on his reading method.
If the reader acquires the "taste" of the book, he will show it in conversation; If he had a flavor in his speech, he would not be able to express his taste in his writing.
So, I think flavor or hobby is the key to reading all the books.
This hobby, like the taste for food, must be selective and personal. Eating a person's favorite food is ultimately the most wholesome way of eating, because he knows that eating these things will work well in digestion.
Reading is the same as eating. "it is a tonic for one person to eat, and poison for others to eat." Teachers cannot force students to read, nor can parents hope their children's hobbies are the same as theirs.
If the reader is not interested in what he reads, then all the time is wasted. And when a man's thoughts and experiences are not yet reached to the point of reading a masterpiece, the masterpiece will only leave a bad taste.
