I don't listen to things outside the window, just read sage books and proverbs. Describe a scholar who only cares about reading and doesn't care about things outside.
"Two ears don't listen to things outside the window, and one heart only reads sage books" comes from Ming Wanli's Ancient and Modern Sages. Some people think that this is the derogatory meaning of feudal literati who only read books on paper and did not care about life, society or even the country.
However, I think this sentence is a compliment. Many of our students today just lack such spirit. Parents do not carry out the spiritual will contained in these two sentences in family education, and good habits are not developed. So the problems in learning become more and more obvious with the increase of school time.
"Don't listen to things outside the window, read only sage books" is to emphasize attention and willpower when studying. Attention and willpower are the two most important indicators to measure the quality of study habits.
