Introduction: This study aims to understand the physical skills of Taiwanese acrobats and to clarify the development of the acrobats' physical concepts and the continuity and creativity of "Fen", the skills that are embedded in their body. Therefore, this study selected Taiwan Stunts Group as the main research object. Methods: This study uses narrative research as a method for interpretation and analysis. The ten participants interviewed are members of the Taiwan Stunts Group. They are half of men and women with the ages of 34-50. They have been studying acrobatics for at least six years and have more than 16 years of practical experience in professional performances, as well as each participant has at least two specialized techniques. The participants have represented the country on many occasions for cultural exchanges overseas. They have also won numerous awards at the International Acrobatic Performance Competitions. Each participant is interviewed about three to six times. Results: Acrobats must develop their unique physical sense in the acrobatic training framework when they are pursuing superior body techniques. This training framework consists of four categories of waist, legs, Somersault, and withstand (Ding). It is also through the "consumption" of time, the "quantity" of operation, and the "trick" of action. Finally, the body of "Fen" is constructed. This Fen body has three following phases: "finding fen→feeling fen→forming fen. Finding fen is to seek out the motion knack by repeating the same training. Feeling fen is to embed the knack into the body by continuous practices. Forming fen is to construct the sense of body by the marking habitus model. This will be influenced by practical experience or physical conditions and constantly adjusted and revised to meet the conditions of thoughts, perceptions and activities, thus giving birth to endless "creativeness". At this stage, the body is almost in a state of "transforming the complex skills into simple ones." Conclusion: "Fen" exists in the physical skills of acrobats. It is a kind of tacit knowledge that cannot be expressed in words. It must be captured or understood through personal experience and understanding, and then imprinted in the body. Mind and thought can integrate and create a physical form of the action condition. [ABSTRACT FROM AUTHOR]
