Yin-yang is the law of the universe, the principle governing all things, the parents of changes, and the origin of life and death.

yin & yang theory
INTERNATIONAL MEIHUA QUAN FEDERATION
YIN & YANG BALANCE
The theory of Yin & Yang is a summarization of the opposition in all things. All that is exciting, hot, dynamic, robust, hyper-functional, bright, invisible, light, upward, outward, and clear belong to Yang (positive). On the other hand, all restraining, cold, static, weak, turbid, and so on belong to Yin (negative).
A similar opposition exists in Heaven and Earth, Sun and Moon, Day and Night, hotness and coldness, male and female, superior and inferior, outside and inside, motion and rest, fire and water, exhale and inhale, excess and deficiency.
All things in the natural world can be divided into Yin and Yang.
The Law of motion of yin & yang
The law of motion of Yin & Yang classifies into three sections.
Interdependence & Opposition
Yin and Yang cannot exist without each other. “Without Yang, Yin cannot grow, and without Yin, Yang cannot develop.”
Waxing & Waning
Yin and Yang are in a constant struggle of waning and waxing in a dynamic equilibrium. Excess or deficiency of Yin or Yang leads to blockages or abnormalities. “While Yin waxes, Yang wanes and vice versa.”
Transformation
Yin and Yang may transform towards the opposite under special conditions. “Yin in overabundance will transform into Yang, and Yang in overabundance will transform into Yin. An overabundance of cold may bring false heat, and an overabundance of heat may bring false cold. “
Application
Yin & Yang Qi Theraphy
Training Qi & Treating Diseases
The spring and summer are Yang, and the autumn and winter are Yin. Exhalation is Yang, and inhalation is Yin. People with excess Yang and hyperactivity of fire should practice Qigong during Yin periods, facing North. The teacher must replenish the Yin to invigorate the Yang and lead Yang to descend to supplement the Yin.
Physiological Body Structure
The upper part of the body is Yang, while the lower part is Yin. The abdomen is Yin: the left part of the abdomen is Yang, and the right part is Yin. The body’s exterior is Yang, and the inside is Yin. The six hollow Fu organs are Yang: gallbladder, stomach, large intestine, small intestine, urinary bladder, and Sanjiao. The five Zhang or solid organs are Yin, the heart, liver, spleen, lungs, and kidneys. The function is Yang for one particular organ, and the substance is Yin. Qi is Yang, and the blood is Yin.
The human body is divided into three pairs of Yin and Yang. The navel is the separation part between Yin and Yang. The section above the navel is Yang, and the one below is Yin. The Baihui acupoint (GV20) on the Governor Vessel Meridian and Huiyin acupoint (CV1) on the Conception Vessel Meridian are the vertical separation points between the left (Yang) and right (Yin) parts of the body. The back of the body is Yang, and the front is Yin.
Qi activities of the body parts, internal organs, and tissues are detected with outgoing Qi at the body surface.
Pathological Changes
If Yin and Yang’s dynamic equilibrium is disturbed, deficiency or overabundance of Yin or Yang will develop, leading to disease. The excess of Yang leads to depletion of Yin and vice versus. The hot syndrome results from either overabundance of Yang or deficiency of Yin. The cold syndrome results from either excess of Yin or deficiency of Yang. After the nature of Yin and Yang is identified, the proper Qigong method is used to regulate the overabundance or deficiency and cure the disease. The treatment method aims to eliminate the excess to replenish the deficit and establish the balance of the body. Intake of cold foods or drinks can lead to an overabundance of Yin, which gives rise to the cold syndrome of the spleen and stomach, giving pain, diarrhea, cold extremities, and fear of cold. Treating the cold with warmth guides the hot Yang Qi towards Zhong Wan (CV12) on the Conception Vessel Meridian and Tian Shu (ST25) on the Stomach Meridian acupoints. The cold Qi is then expelled from the body from Zusanli (ST36) on the Stomach Meridian and Yinling Quan (SP9) on the Spleen Meridian.
The Book of Changes
In medicine, the Yin and Yang theory is the organizing principle in the correlation of all medical information.
The I Ching is about the constant flux and permanence of the systematic correspondence in the universe. “Jing” means “great book” and “I” is a pictogram of the sun and the moon in combination, which means Yin and Yang. The universe is in movement or transformation at every moment. Life itself is a process of never-ending change from birth to death. The I Ching forms the basis for all Chinese science and it is a fundamental part of Chinese cultural expression.
No aspect of Chinese civilization such as
metaphysics, medicine, government,
or art has escaped its imprint.
Yin and Yang
Everything is included in the Yin & Yang
Body Posture
Posture is essential in Qigong exercises. Upward, downward, left, right, forward, backward, bending, reflexing, stretching, raising, descending, opening, and closing movements are part of the Yin and Yang theory posture. For hypertension patients, it is advisable to sit straight with the mind focused on the navel or Yong Quan (KI1) on the Kidney Meridian acupoint.
Motion - Stillness
Motion and stillness belong to Yin and Yang. Motion is Yang, while stillness is Yin. In Qigong practice, motion can be transformed into stillness, and stillness can be transformed into motion in spontaneous movements known as production of motion due to extreme stillness and production of Yang due to extreme Yin.
Breathing
Breathing regulation follows Yin and Yang laws, ascending, descending, entering, and exiting. Inhaling fresh air through the nose is a Yang activity and exhaling through the mouth is Yin.
Mental Health
Mental health is key to Qigong practice and Yin and Yang balance. Yang Qi is stored at the Yin hour in a hot lesion. This practice uses mental visualization. In winter, visualize entering the body Yang warming Qi while in summer cooled Yin Qi.
Meihua Quan is based on the practice and inheritance of martial arts. The martial arts exercises are both broad and profound, simple and effective, and fully embody the characteristics of simplification and the magic of the Dao. They are rooted in the most profound Chinese national cultural heritage.
Meihua Quan adheres to deep philosophical principles applying the theory of Yin and Yang and the Five elements. It has evolved from the most essential five postures to a boxing method that integrates various leg movements, hand shapes, steps, and body and extends to different weapon exercises, battle formation tactics, and the unique Meihua Quan poles method.
