Yehulingkou is an important pass of the Great Wall of Xuanfu Town West Road in the Ming Dynasty. It was also the main road to the outside of the Great Wall during the Liao, Jin, Yuan, Ming and Qing dynasties. Yehulingkou is more than 1,600 meters above sea level. Standing on the top of the mountain, you can see the majestic Ming Great Wall soaring westward to the top of the mountains at the junction of Zhangbei and Wanquan, winding southeastward among the steep mountains leading to Zhangjiakou Dajingmen; to the northeast, you can see the remains of the Qin Great Wall hovering over the deep ravines and cliffs, which is spectacular. Yehuling is the throat of the traffic leading to the outside of the Great Wall. With the danger of Yehuling, it can attack when advancing and defend when retreating. It has been a military fortress and a place of contention for military strategists since ancient times. For this reason, a poet wrote: "Yehu is a famous place in ancient and modern times, with dangerous roads and high mountains on the edge of Yunhan. Don't be surprised that the military strategists fight for this place, and drive straight to control Youyan."

Interpretation of Yehulingkou from the perspective of Eastern philosophy As a military fortress in history, the existence of Yehulingkou itself contains the ideas of "yin and yang" and "five elements" in Eastern philosophy. In Eastern philosophy, yin and yang represent the unity of opposites of all things in the universe, while the five elements (gold, wood, water, fire, and earth) symbolize the five basic elements of nature and their interactions. The geographical location of Yehulingkou is both the "yin" of defense and the "yang" of offense, reflecting the philosophical idea of the mutual generation and mutual restraint of yin and yang. At the same time, the combination of its natural environment and military facilities also reflects the principle of the mutual generation and mutual restraint of the five elements. For example, the natural environment of rocks (earth) and water (rivers) interacts with the artificial factors of metal (weapons) and fire (beacon fire), which together constitute the defense system of Yehulingkou. Interpretation of Yehulingkou from the perspective of Western philosophy From the perspective of Western philosophy, Yehulingkou can be interpreted as a philosophical thinking of "existence and time". In his book Being and Time, German philosopher Heidegger explored the relationship between "existence" and "time", and believed that "existence" is understood and experienced through "time". As a witness to history, the existence of Yehulingkou itself is a trace of time. Every brick and tile carries the story of the past, reflecting human thinking on security, defense and strategy in a specific historical period. At the same time, the existence of Yehulingkou has also triggered philosophical thinking on "freedom" and "restriction". It is both a symbol of freedom (such as free march and free trade) and a manifestation of restriction (such as military defense and border control). This contradiction reflects the discussion of freedom and restriction, individual and collective relationships in Western philosophy. In summary, whether from the perspective of the Yin-Yang and Five Elements of Eastern philosophy, or the perspective of existence and time, freedom and restriction in Western philosophy, Yehulingkou contains rich philosophical implications and is a unique landscape where history and philosophy meet.
