Look at qi for good or ill luck.

You can usually tell by color. The colors of the gas in all directions are: oriental wood, and the gas is cyan; The south is fire and the gas is red; The west belongs to gold, and the gas is white; The north belongs to water, and the gas is black; The center belongs to the soil and the gas is yellow.

Seeing qi not only means "seeing", but also often cooperates with experienced people to "smell". Regardless of the old and the new, the Yin and Yang family naturally forms a unique gas field because of its mountains, sand and water, its internal and external structure and its master's Yin and Yang elements. In addition to being visible to the naked eye, they can also smell the different smells of this wild gas.

Qi is a common concept in Yin and Yang studies. Thinkers in China during the Spring and Autumn Period and the Warring States Period abstracted the concept of qi, making it the basic element of all things in the world, with the characteristics of flowing like gas. It is believed that the life energy or power possessed by human beings and all living things is also called qi, and everything in the universe is the result of the change of qi operation. Traditional Chinese medicine believes that qi is the first line of defense of human body, which gathers in the body to protect viscera, but flows out on the skin surface to prevent the invasion of foreign pathogens from causing diseases.

Etymology: Qi comes from the ancient word "Qi", which originally meant cloud qi. It's a hieroglyph, which means breath and breath [2] and rice [3]. It was quickly extended to include weather, climate, solar terms, smell, even ethos and popularity. , and also developed many variants, such as Wei, Wei, and gradually became Qi after the Tang Dynasty.

After the Song Dynasty, in order to distinguish innate qi from acquired qi, Taoist thinkers used the ancient word "Kuai" to express innate qi and infinity, and regarded qi as acquired qi, which was called Taiji. The meanings of these two words are separated again. But in addition to Taoist literature, it is usually summarized by Qi.

Traditional Chinese Medicine: In traditional Chinese medicine, the combination of qi and blood is called' qi and blood', which is considered as the most basic energy to constitute the human body and maintain life activities, and also has the meaning of physiological functions. Qi is similar to body temperature, so when the internal and external environment changes, it may be disturbed and affect human health. Traditional Chinese medicine believes that qi can be subdivided into primordial qi, ancestral qi, nourishing qi and defending qi according to its different functions, characteristics and movements.

Yin and Yang Studies: The ancients believed that the interaction between heaven and earth was the basis of the growth of all things. This truth can be known from the change of cold and heat, the movement of the sun and the moon, and the alternation of day and night. Grasping this law is the foundation of geomantic omen. We must first determine the position of the door, that is, where the door opens, and take this position as the orientation. The ancients believed that the living environment can not be separated from qi, and only with qi can there be life. As the saying goes, people strive for a sigh of relief, and Buddha strives for a furnace of incense. This is how people live. The flow of qi will inevitably produce an aura, and the door is the only way to get in and out of the aura. Put an eight-foot mirror in a prone position. After that, according to the birthdays of all the residents in the house, add a seal to the seal book respectively, and use eight-foot photos to prove it. Born in March to May of the lunar calendar, you need to add three seals of "Wen Zhu, Zhou Zhou, Wuyin Divide Gold". Born from June to August in the lunar calendar, you need to add three seals: "Hong Jiu Jinsheng, Mu Baijing, Ishida Zuozhi". Born from September to 1 1 month of the lunar calendar, you need to add three seals of "Chihiro, Sparse and Rizu". Those born between February and February of the 65438 lunar calendar should be stamped with three seals of "Otonashi Kyoko, Satoshi Ishida and Fusang Umbrella". Only in this way can we activate the fortune and maintain wealth and health. The ancients said to seek advantages and avoid disadvantages. Therefore, in addition to lying down, the ancients also used the geomantic omen of eight houses to determine the sitting direction of the house according to the orientation of the gate. When we stand in the middle of the room and face the door, the orientation we face is "direction", while the orientation opposite to "direction" is "sitting". Regardless of the shape of the house, the orientation of sitting and facing must be relative. For example, if the gate faces west, the house will sit east facing west. Eight directions correspond to eight kinds of divinatory symbols, namely, dry, watching, gen, earthquake, ten-day, calendar, Kun and right. The "sitting" position of a house determines what it belongs to. The door of the house faces east, sitting in the west, and the west is the "shock" of gossip. That house is an earthquake house. Specifically: 1, the house in the east is the earthquake house, and the gate is in the west. 2. The house in the southeast is Xunfu, and the gate faces northwest. The house in the south is far from the house, and the gate faces north. 4. The home in the southwest is Zhai Kun, and the gate faces the northeast. The house in the west is opposite to the house, and the gate faces east. 6. The house in the northwest is a dry house with the gate facing southeast. 7. The house in the north is Kanzhai, and the gate faces south. 8. The house in the northeast is a mansion with its gate facing southwest.

Traditional Chinese medicine: smell and taste: in traditional Chinese medicine, it refers to the special smell of drugs containing volatile substances.

Modern explanation: 1959, Qin Bowei put forward the theory of "qi substance". 1962, Luo Shibiao put forward the function theory of qi. In the same year, (1962), Beihai Wei put forward the ambiguous theory of qi. In addition, there are Li Dexin's theory that Qi is the unity of matter and function, Huang Kunyi's theory of human body gas field, Shao Li's theory of Qi and entropy flow, and Wu Banghui's theory of gas sequence parameters. During the period of 1996, Deng Yu and others thought that the Qi of TCM was the unity of the three elements of life activities "information-energy-matter" that have been discovered and not yet discovered in modern biology.

The * * * vibration theory of blood circulation holds that in the * * * vibration phenomenon of blood circulation, blood vessels have their specific * * vibration frequencies, and organs and acupoints also have their specific * * vibration frequencies. Organ or acupoint and artery have frequency division due to coupled vibration. All human organ systems have their own frequencies. If organs with the same harmonic vibration are classified into the same category, then the relationship between zang-fu organs and meridians is naturally obtained. The five internal organs and their meridians belong to low frequency, so they belong to yin; The six fu organs and their meridians belong to high frequency, so they belong to Yang. According to the vibration theory, "Qi" is the expression of pressure energy produced by the heart. When an organ system is deficient in qi, the pressure is also insufficient. When arterioles in organs are opened, blood can't be injected into microvessels and then nourish tissues. Therefore, this organ system will be ischemic because of qi deficiency, and naturally it will lack nutrition, hypoxia and resistance, leading to the accumulation of metabolic waste. After a long time, all diseases of the human body can come from this.
