There are three famous sayings by Wang Guowei in his study and scholarship, which he calls the three realms, namely, "The west wind withered the green trees last night. I went up to the west tower alone and looked at the end of the world." This is the first realm. "The belt becomes wider and wider, but I don't regret it at all. I feel haggard because of the loss of my clothes." This is the second state. "The crowd searched for her thousands of times, but suddenly looking back, she was in a dimly lit place." This is the third realm. ". The "Three Realms" are his experience of reading and his tips for reading.

The first realm is borrowed from Yan Shu's words. It means that to do knowledge, you must first have the spirit to climb the heights. We must do everything we can to climb high and look far, "see all the way to the end of the world", broaden our horizons, and seek the treasure of knowledge.

The second realm, to borrow Liu Yong's words, is in the world. In the process of studying, you have to endure hardships and not be afraid of losing a few pounds of meat.

The third realm is to borrow the words of Xin Qiji, which means that as long as you have a broad knowledge and persist in studying repeatedly and deeply with perseverance, If you read carefully and think deeply, at a certain time, you will suddenly become enlightened, discover something, and create something.
