Thanks to Zhu's detailed explanation of "Three Centers"

There are three ways to read, namely, heart, eyes and mouth. If the heart is not here, the eyes will not look carefully, and the mind will not be single-minded. It will only read aloud, never remember, and never remember for a long time. Of the three, the heart is the most urgent. Since the heart is here, won't the eyes be there?

Song Zhuxi's "Rules of Training and Learning, Reading and Writing".

There are three ways to read: heart, eyes and mouth.

China's traditional reading method pays attention to three words: understanding with the heart, seeing with the eyes and reading with the mouth. These are several important links, and Zhu's summary is very accurate. Spiritual enlightenment refers to thinking, and only through "enlightenment"-repeated taste can we understand the essence of books; Only by keeping a close eye on the Expo can we expand our knowledge; The mouth should read the sound, so as to mobilize the comprehensive functions of hearing and vision, enhance memory and help understanding. These three "Tao" are accurate, concise, boring and thought-provoking, thus becoming the guidelines of later scholars. The San Zi Jing says, "There are three ways to read. Heart and mouth, believe everything "is summed up from this sentence. "
