What are the clues to express feelings in the former Chibi Fu?

The writing of Qian Chi Bi Fu is based on the author's emotional change of "happiness-sadness-happiness".

This essay skillfully combines emotion, scenery and reason, embeds emotion in the scenery, and matches the ups and downs of emotion with the changes of writing style, such as flowing freely and naturally. The article always focuses on the feelings and enlightenment brought by the three natural images of wind, moon and water in Chibi. Firstly, the elegant pictures of "the breeze in Xu Lai is stagnant" and "the dew is crossing the river, and the water meets the sky" are depicted, and then the beautiful scenery in front of us triggers the broad-minded feeling of "floating like an independent world". The scenery of water, moon and wind is the proof of the following reasoning. Then, depending on the success or failure of historical figures, compared with the argument of "guest", with the idea of "admiring the infinity of the Yangtze River", with the idea of "holding the bright moon for a long time", with the idea of "echoing the legacy and hating Taiwan", and with the natural scenery, the passivity and pessimism of "guest" are expressed. Finally, through the metaphor of water and the moon, it shows that things have the philosophy of "change" and "unchanging". The author uses natural beauty such as "the breeze on the river" and "the bright moon in the mountains" to express his enthusiasm and positive and optimistic spirit for life. The full text is clear, smooth, comfortable and plump, and discusses the profound philosophical connotation given to the scenery; The full text makes philosophy present a vivid and sensible image, and at the same time expresses the author's feelings, so that emotion, scenery and reason are integrated and complement each other. ?
