"A good reader does not seek a deep understanding" comes from "The Biography of Mr. Wuliu" written by Tao Yuanming of the Jin Dynasty. The original text is "A good reader does not seek a deep understanding; every time he understands something, he happily forgets to eat." It means that reading is just a matter of reading. Seek to understand the gist and appreciate the artistic conception of the book, without chewing on the words or focusing on the words.
