2、 Main content
The principle of yin and yang and the auspiciousness and inauspiciousness of residential buildings:
The “Zhaijing” is based on the principles of the Eight Trigrams of King Wen in the Book of Changes, with reference to the theories of Heavenly Stems and Earthly Branches, to discuss the “auspiciousness and inauspiciousness” of the eight directions of Yangzhai and Yinzhai.
Propose the theory of “mutual support between people and houses, connecting heaven and earth”, believing that there is a mutually influential relationship between people and houses.
Classification of Yangzhai and Yinzhai:
The Yangzhai and Yinzhai mentioned in the “Zhaijing” do not refer to cemeteries and residential areas, but rather to two types of residential buildings. The judgment method is as follows: those who move from the southeast to the northwest, from the south to the north, from the west to the east, from the west to the east, and from the northwest to the southeast, are referred to as Yangzhai; On the contrary, it is a haunted house.
The division between yang and yin houses reflects the idea of yin-yang interaction and yin-yang balance.
Directional order and various taboos:
Elaborated in detail the directional sequence and auspicious taboos of residential construction, including regulations on house orientation, door and window positions, room layout, and other aspects.
Emphasize that residential buildings should conform to nature and avoid human damage to the harmony and balance of the environment.
Yangzhai Feng Shui auspicious and inauspicious evaluation system:
Propose four evaluation criteria for determining the good and evil of a house: based on whether yin and yang are in harmony, based on the size of the house’s form and layout, based on the taboos of choosing a prosperous or declining day, and based on the order and internal structure of building construction.
Emphasis is placed on the influence of the internal and external forms of a residence on feng shui, such as the shape of the house, the walls of the courtyard, and the prosperity of the six livestock, all of which are closely related to the auspiciousness or inauspiciousness of the residence.
Requirements for building height and size regulations:
According to the 24 directions, the requirements for the height and size regulations of buildings in each direction are explained in detail, divided into two categories: Yin houses and Yang houses.
These regulations aim to ensure harmonious coexistence between residential buildings and their surrounding environment, and to avoid human destruction of the balance of the natural environment.

3、 Core idea
The core idea of the “Zhai Jing” is to emphasize the mutual influence relationship between people and housing, as well as the harmonious coexistence between housing and the surrounding environment. By observing and analyzing factors such as the orientation, layout, and shape of residential buildings, one can predict and judge the auspiciousness or inauspiciousness of residential buildings and the direction of human destiny. At the same time, the “Zhaijing” also advocates the concept of conforming to nature and avoiding human destruction of environmental harmony and balance.

4、 Practical significance
The Zhaijing not only has theoretical value, but also has profound practical significance. It provides a methodology for observing and analyzing housing, helping people understand the impact of housing on human life and destiny. Meanwhile, the relationship between residential properties and their surrounding environment revealed by it can provide useful references and guidance for urban planning, architectural design, home layout, and other fields.

5、 Limitations and Modern Applications
Although the “Zhai Jing” holds an important position in the field of feng shui, its theoretical system also has certain limitations. Some viewpoints and theories lack scientific basis and empirical support, so they need to be treated with caution in practical applications. In modern society, the application of traditional feng shui such as the “Zhai Jing” needs to be improved and perfected by combining modern scientific knowledge and technological means to better meet the needs of modern society. At the same time, we also need to maintain a rational and objective attitude, not blindly blindly believing in Feng Shui, but understanding and inheriting it as a culture and tradition.

As a classic feng shui work, the “Zhaijing” has profound theoretical and practical significance. However, when applying its theory, we should also rationally view its limitations and combine modern scientific knowledge and technological means to improve and perfect it.
