A SYSTEMATIC REVIEW OF 328-FORM TAI CHI CHUAN: TRADITIONAL YANG CHENGFU THEORETICAL FRAMEWORK, SIX-CHARACTER BREATH REGULATION, AND SYMMETRICAL YIN-YANG CLOSED CULTIVATION SYSTEM FOR PHYSICAL AND MENTAL HEALTH PROMOTION

Tai Chi Chuan (Taijiquan) is a traditional Chinese mind‑body intervention widely acknowledged worldwide for its superior efficacy in improving physical balance, mitigating psychological stress, regulating visceral functions, and nurturing internal qi energy. As an innovative and orthodox Yang‑style Tai Chi system, the 328‑form Tai Chi Chuan features a fully symmetrical left‑right Yin‑Yang closed‑loop cultivation framework, which derives from the authentic lineage inheritance of Yang Chengfu, Li Yaxuan, Lin Mogen, and Loo Tjing Yung. Distinct from conventional simplified Tai Chi routines that are limited by unilateral movement patterns and fragmented internal cultivation mechanisms, this integrated system combines symmetrical posture training, six‑character therapeutic respiration, differentiated thoraco‑abdominal breathing kinematics, five‑zang visceral modulation, and hierarchical spiritual refinement. It comprehensively embodies the core theoretical connotations of traditional Yang‑style Tai Chi. This systematic review elaborates on the authentic inheritance lineage, unique structural advantages, thoraco‑abdominal respiratory characteristics, internal operational mechanisms, multilayered cultivation framework, standardized practice protocols, and tabulated reference datasets of the 328‑form system. The results demonstrate that the 328‑form system perfectly instantiates Yang Chengfu’s canonical Tai Chi theories, realizes the organic integration of external physical posture correction, coordinated thoraco‑abdominal qi circulation, visceral health maintenance, and spiritual discipline, and establishes a standardized, replicable, and globally promotable orthodox Yang‑style mind‑body cultivation system.
