This is Wang Guowei's "Three Realms" theory

The master of Chinese studies Wang Guowei used the agility of a poet, the sensitivity of an esthetician, and the insight of a philosopher to connect Yan Shu's " "Butterfly Loves Flowers", Ouyang Xiu's "Butterfly Loves Flowers", and three sentences from Xin Jiaxuan's "The Green Jade Case" (these three sentences are: "Last night the west wind withered the green trees. Go up to the tall building alone and see the end of the world." "My clothes are getting wider and I don't regret it anymore, I'm haggard because of the loss of Yi"; "I searched for him a thousand times in the crowd, but when I turned around, I suddenly saw that person there, in a dimly lit place"), connecting these three famous quotes that were originally unrelated. The theory of "three realms" crystallizes the secrets of success of countless great businessmen and great scholars in history into literary images.

The first realm, "Last night, the west wind withered the green trees. Go up to the tall building alone and see the whole road to the end of the world." Last night, the strong west wind blew, and the leaves on the big green trees withered one by one. A little confused, a little desolate. This is an image of change. The time sequence is changing, the objects are changing, the world is changing, and the mentality is also changing. I feel the arrival of autumn in the drifting of "a leaf", and "climbing up a tall building alone and looking to the end of the world" seems to see the winter after autumn and the brilliant spring that follows.

In the second realm, "I will never regret it as my clothes get wider and wider, and I will become haggard because of the beauty." This is a kind of persistence in pursuing the truth unswervingly on the established path, and for It's "not regretful", but it's "haggard". There is not only physical suffering here, but also mental tempering. As Wang Guowei said, one can even "sacrifice the well-being of one's life" with "no regrets".

The third level: "The crowd searched for him thousands of times, and when I turned around, I suddenly saw that person there, in a dimly lit place." During the Lantern Festival, there are so many tourists, the lights are like the sea, and the flowers are like the tide. It's like this I searched for the scene thousands of times, but couldn't find it. Finally, when I looked back suddenly, I found the beauty in the dim light.

In other words, it is so wonderful to find the path in the right direction, pursue it persistently, go through all kinds of hardships, and finally become enlightened, seek "truth" and "yes", and then merge your findings into the long river of truth. Glad!
