As the saying goes, \”I am not afraid of high and low houses, but I am afraid of the style of passing through the hall.\” What is the conclusion of the ancestors?

In the bluestone alley in the water town of Jiangnan, an old carpenter is repairing a century-old house. He held a Ruler in his hand, carefully measuring the size of the door and murmured to the screen that was about to be installed: \”This style of walking through the hall is not good.\” This scene vividly plays the ancient wisdom of \”not afraid of the high and low houses, but afraid of the style of walking through the hall\”. This seemingly simple phrase actually contains the ecological philosophy of unity between man and nature in Chinese architectural culture.

1. Physical laws under the surface of wind and water

In the traditional style water theory, \”passing the hall style\” is regarded as a concrete manifestation of \”evil atmosphere\”. The ancients observed that when airflow forms a silence inside the building, it will not only sweep away the heat and air inside the room, but also create a dangerous negative area in a specific location. The circular structure of Fujian soil buildings cleverly transforms the wind through the hall into a flow circulation of the circular building, which not only ensures the wind through the wind without forming a straight flow. This design concludes with the modern principle of fluid force: when the airflow channel suddenly narrows, the flow rate accelerates and leads to a drop in the air pressure. This is exactly the physical basis of what the Chinese medicine calls \”evil winds entering the body\”.

The horse walls of Hui-style buildings are not only fireproof The facilities are even more exquisite air flow adjustment devices. The walls that fall from high and low will cause turbulence to generate during the ascent, resolving the impact force of the straight airflow. The curved corridor design of Suzhou Garden Forest decomposes the wind through multiple turns into a gentle wind, achieving the effect of \”no traces when the wind is left\”. These crystals of wisdom show the ancients\’ direct grasp of Bernoulli\’s law.

Certification of modern building physics, when indoor speed When it exceeds 0.3 meters/sec, the human body will feel uncomfortable. The screen wall design of Beijing Siheyuan can reduce the speed of the hall through more than 70%. This method of changing the air flow path through barriers,The discussion on the wind tunnel experiment of contemporary architecture is inconsistent.

2. Environmental control in medical knowledge

The Huangdi Neijing records: \”It is sometimes easy to avoid evil spirits.\” Chinese medicine theory regards the trance-passing style as a pathogenic factor, and this recognition is ahead of schedule. Modern medicine has found that continuous airflow shock can cause a local temperature drop of 2-3°C in the human body, which is the most active temperature area for the cold virus. The interior fan design in traditional residential houses can not only ensure air circulation, but also control the wind speed to a safety range of 0.1-0.2 meters/sec.

The trekking gate in the southern area is to control the passage of the hall classic case. This activity door composed of 13 round woods can adjust the ventilation volume according to the season. The wind is formed when the summer is fully opened, but the clever design reduces the wind speed; when the winter is half closed, it not only maintains the wind but also prevents the cold current. This adjustable wind system is more in line with human needs than the constant temperature air conditioning of modern buildings.

Contemporary environmental medicine research shows that ideal indoor The airflow should form a \”rotary\” cycle. The patio design of an Yin house in Yunnan forms a slow rising airflow through heat pressure difference, allowing fresh air to enter from the bottom and dirty air to be discharged from the top. This natural ventilation method is fully in line with modern health standards.

3. Survival philosophy in cultural metaphors

\”Tao in the hall style\” reflects the \”neutralization\” idea of ​​Chinese culture. In the five-in-one courtyard of Joe Courtyard in Shanxi, each door corridor has a wrong central axis. This \”wrong door and evil way\” design is to avoid direct airflow. The twists and turns of the building space are not only awe of natural forces, but also a philosophical manifestation of \”full of appeal and benefit\”.

In the Jiangnan garden forest, the leaking windows are not only decorations , it is also a buffer device for airflow. The \”Who is sitting with\” in the Humble Administrator\’s Garden decomposes the style of the hall into a bright and clear style through the combination of the moon-hole door and the flower window. This space treatment that is \”turned into softness\” implies the wisdom of \”using softness to overcome the softness\”.

The Bagua shape of the guest house, Transform the wind through the hall into a flowing field for circular buildings. This design concept transcends simple functional needs and rises to the level of cosmic awareness of \”the unity of heaven, earth, man and man\”. Architecture has become a medium that connects the world, showing the unique spatial philosophy of China.

Standing in front of the glass curtain of contemporary buildings, looking back Traditionally, those seemingly simple manufacturing wisdoms are increasingly showing value beyond the times. When we pursue building efficiency, do we lose the ability to talk to nature? The saying \”I am not afraid of high and low houses, but I am afraid of passing through the hall\” is not only a summary of architecture technology, but also a inheritance of survival wisdom. It reminds us that a truly livable environment lies not in the accumulation of technology, but in the deep understanding and clever use of natural laws. The ecological wisdom contained in the tiles is a precious inspiration left by Chinese traditional buildings to modern society.
