Huang, a poet in the Song Dynasty, famously said: If you don't study for three days, it's a pity to abandon it. Lin Yutang interprets this sentence as: If you don't study for three days, others will think your language is tasteless and your face is disgusting. A person who doesn't like reading is often bored, so he is not liked. Zhou explained that if he didn't study for three days, he would feel ashamed, ashamed to talk to people and ashamed to meet people. I feel that when I don't study for three days, it's like being drained of my soul and losing my confidence when I give lectures to students. The language is dry, the writing is not satisfactory, and the classroom is lifeless. I feel that my classmates are suffering from the following punishments. My face is an abominable description, elegant and uneasy. I feel guilty that I owe too much debt to my students. Listening to my favorite music in my ear, holding a book I chose at random in my hand, my heart sank in, and I enjoyed it very much and was very comfortable. I think, after reading this book, my face and eyes will be full of confidence and satisfaction. In this way, reading can actually have a beautiful effect. I hope it will help you, and I hope it will be adopted. Thank you.
