Section 1: What Is Qi?
Meaning of Qi
Qi (pronounced “chee”) is a foundational concept in traditional Chinese philosophy and medicine. It refers to the vital life force or energy that flows through all living things. According to Chinese thought, qi animates the body, supports mental clarity, and maintains balance between physical and emotional health.
When people talk about qi or chi, qi is the original Chinese spelling used in modern academic and medical contexts.
How Qi Is Used
Qi is most commonly used in:
- Traditional Chinese Medicine (TCM)
- Acupuncture and acupressure
- Qigong practices
- Tai Chi theory
- Academic and professional writing
In these settings, qi describes how energy flows through pathways called meridians. Blocked or weak qi is believed to cause illness, while balanced qi supports wellness.
Where Qi Is Used (Language & Grammar)
- Country of origin: China
- Language system: Pinyin (modern Romanization of Mandarin Chinese)
- Preferred in: Academic, medical, and professional writing worldwide
Since the 1950s, China officially adopted Pinyin, which standardized qi as the correct spelling in English-language scholarship.
Examples of Qi in Sentences
