There are three famous sayings in Wang Guowei's study, which he calls the Three Realms, namely: "The west wind withered the green trees last night. Go to the west building alone to see the world. " This is the first place. My belt is getting wider, and I am haggard because of Iraq, and I don't regret it. This is the second world. The crowd searched for her for thousands of Baidu, and suddenly looking back, the man was in the dim light.' This is the third realm. "This is how Wang Guowei himself came in." "Three Realms" is his reading experience and his reading know-how. The first realm, to borrow Yan Shu's words, is learning. First of all, we must have the spirit of bravely climbing the peak. We must try our best to climb the mountain and overlook it, "broaden our horizons", broaden our horizons and look for the treasure of knowledge. The second realm is to borrow Liu Yong's words, saying that in the process of learning, we should bear hardships and not be afraid of losing a few pounds of meat. The third realm is to borrow Xin Qiji's words, saying that as long as you are well informed, persist in repeated, in-depth and persistent research, and be familiar with it, you will be suddenly enlightened, and you will discover and create something at a certain time.
