What are the three stages of life written by Wang Guowei?? Urgent: Thank you

The first stage is taken from Yan Shu's "Butterfly Loves Flowers": "Last night, the west wind withered the green trees, and I went up to the tall building alone and looked at the end of the world." The second stage is Liu Yong's "Butterfly Loves Flowers": "The clothes and belts are gradually widened, and I will not regret it, and I will make people haggard for Yi. The third stage is taken from Xin Qiji's "Qingyu Case Yuan Xi" "The crowd looked for him thousands, and suddenly looked back, but the person was there, and the lights were dim. ”

The original text is as follows: "Those who have achieved great careers and asked questions in ancient and modern times must pass through three realms. 'Last night, the west wind withered the green trees, went up to the tall building alone, and looked at the end of the world', this first realm also;'The belt gradually widens and does not regret it, and makes people haggard for Yi', this second realm is also;'The crowd looked for him thousands, and looked back at dusk, but the person was there, and the lights were dim', this third realm is also.

None of these words are big words, and people can't say them. However, if you interpret the words in this sense, I am afraid that Yan and the European princes will not allow it. ”

Wang Weisheng was in the later period of Wu Zetian's reign, and his youth went through Zetian, as well as the three dynasties of Zhongzong and Ruizong after the restoration. This was an extraordinary period when Li Tang and the Wu clan had a fierce struggle, and during this period, they were mixed in with female careerists such as Empress Wei, Princess Taiping, and Princess Anle. Fortunately, Wang Wei was still young at this time and was studying in primary school in Yuncheng.

By the time he entered the customs at the age of 15 to seek the opportunity to advance, he was already in the era of the famous wise leader and lotus flower emperor Tang Minghuang.

That is to say, although he is a native of Shanxi, Wang Wei's main life experience is in other places, and he has caught up with the prosperous era of the Chinese Empire——— Kaiyuan and Tianbao eras. As a scribe, he followed a path of seeking official positions, which made his "road map" have to be surveyed and mapped around the eastern and western capitals of the Tang Dynasty (Luoyang and Chang'an). As a deeply poisoned Buddhist, Wang Wei never forgot to go into hiding.

Seek to become an official to obtain the ability to support the old mother and weak brother, and run to the mountains and forests to obtain peace of mind. Wang Wei's life was spent in a hurry between Zhongnan and Wei Que.

Wang Guowei, a master of Chinese studies, summed up the three stages of writing in three sentences in his "Words in the World": the first stage is "last night the west wind withered the green trees, alone on the tall building, looking at the end of the world", the second stage is "the belt gradually widens and does not regret it, and the people are haggard for Yi", and the third stage is "the crowd is looking for a thousand others, and suddenly looking back, but the person is in the lamplight".In the first stage, the subject of perception focuses on a specific object, such as a fisherman who forgets the distance and is at a loss; In the second stage, the perception is in a state of spontaneous and exuberant activity when the fisherman suddenly encounters the peach blossom forest and wants to exhaust the forest; The third stage is a leap in understanding achieved after the above two stages.

If the fisherman enters the peach blossom spring, he suddenly opens up and is beautiful. This is the so-called "epiphany" of Zen Buddhism
