1. Wu Xia Amen (a metaphor for having little knowledge). Wuxia: now south of the Yangtze River in Jiangsu; Ameng: refers to Lu Meng who lives in the next corner of Wu. It is a metaphor for people who have little knowledge.

2. Look at it with new eyes (look at it with new eyes). "Look with admiration" was originally written as "look at it with admiration", which means to get rid of the old views and look at it with new eyes. It first appeared in Pei Song's notes in "Three Kingdoms? Wu Zhi? Lu Meng Biography".

3. Parting for three days (describing the time when people are separated is very short).

The original text tells that Lu Meng was originally a martial artist. After Sun Quan encouraged him to learn, he gradually gained knowledge. Used together with "to look at with admiration", it describes great progress and a new look.

4. Opening a book is beneficial (a metaphor for reading is useful).

Open the book: open the book, referring to reading; benefit: benefit, gain. Opening a book is always beneficial. It is often used to encourage people to be diligent and studious, and reading more will benefit them.

At the beginning, Quan said to Lu Meng: "You are now in charge of Tu, so you must learn from it!" Meng Ci said that there were many things in the Israeli army. Quan said: "Why do you want me to study the classics and become a doctor? Instead, you should dabble in it and see the past. You have many things to do, so who is alone? Reading alone is of great benefit." Meng Nai began to study.

When Lu Su passed by Xunyang and discussed with Meng, he was shocked and said: "The talent you have now is not as good as returning to Wu Xia Amen!" Meng said: "I have been separated for three days, and I am even more impressed. Wait, brother, why are you late to see what happened?" Su then paid homage to Meng's mother and left as friends.
