Yin–Yang · Complementary Polarity / Dynamic Balance
【中文】
阴阳，指一切事物中相对而互补的两种基本属性与运行倾向。
它们并非彼此对立的实体，而是在统一整体中相互依存、相互转化的关系结构。
【English】
Yin–Yang refers to the complementary polar qualities present in all phenomena.
They are not opposing substances, but interdependent aspects within a unified whole, continuously interacting and transforming.
【中文】
阴阳是中国传统思想中最基础、也最具普遍性的认知框架。
任何现象一旦进入变化与运行的层面，必然呈现出阴与阳的相对关系。
阴阳并不是绝对的分类，而是相对、流动、可转化的。
同一事物在不同条件下，既可以表现为阴，也可以表现为阳；阴中含阳，阳中含阴，二者始终处于动态平衡之中。
在太极修行与养生实践中，阴阳体现为身心内外、上下、动静、虚实等关系的协调。
修行的关键不在于偏向某一端，而在于识别并调和阴阳，使整体运行趋于中正与和谐。
【English】
Yin–Yang is one of the most fundamental and universal frameworks in classical Chinese thought.
Whenever phenomena enter the realm of movement and change, they naturally display yin–yang relationships.
Yin and yang are not fixed categories but relative, fluid, and transformable.
The same phenomenon may appear as yin or yang under different conditions; yin contains yang, and yang contains yin, maintaining a dynamic balance.
In Taichi practice and cultivation, yin–yang manifests as the coordination of inner and outer, upper and lower, movement and stillness, and fullness and emptiness.
The aim is not to favor one side, but to recognize and harmonize yin and yang so that the whole functions with balance and integrity.
阴阳是相对关系与变化规律，而不是静止的二元划分。
Yin–Yang describes relational dynamics and principles of change, not rigid binary divisions.
