Form and potential are the most basic and important issues in calligraphy art, and the situational theory originated from Sun Tzu's Art of War. During the Spring and Autumn Period and the Warring States Period, a hundred schools of thought contended, and military strategists were famous for their knowledge. "Han Xing, Sean and Han Xin ordered the Art of War and used 182 schools". Ban Gu wrote The History of Chinese Literature, which divided the art of war into four categories: one strategy, two potentials, three yin and yang, and four techniques.
According to the records in Pei Songzhi's Notes on the Three Kingdoms, the required books recommended by Zhuge Liang to Liu Chan are legalist works and military books, and the books that Sun Quan suggested that Lv Meng "read urgently" are also historical books and military books. This shows that during the Han and Wei Dynasties, people were very keen on the art of war.
At Heron Hill, Don Wang Zhihuan.
The sun sets slowly near the western hills, and the Yellow River flows into the East China Sea.
By going up one flight of stairs, look further.
The setting sun slowly sinks beside the western hills, and the surging Yellow River rushes to the East China Sea. If you want to see the scenery of Wan Li, you must climb a higher tower.

The extraordinary ambition of the poet in this poem reflects the enterprising spirit of the people in the prosperous Tang Dynasty. Among them, the first two sentences are what you see. "The Mountain Covers the Day" is about the view, the mountain and the scenery seen when climbing the building, and "The River with the Ocean Discharging Gold" is about the close-up view, the water is spectacular and magnificent.
Here, the poet captured the rivers and mountains of Wan Li in a very simple and plain language with just ten words; Later, when people read these ten words a thousand years later, they felt that their brains were wide open. Looking into the distance, a touch of sunset sank to the endless rolling mountains in front of the building and disappeared into Ran Ran at the end of the field of vision. This is the sky view, the distant view and the western view.
