Inside the Eternal Spring Instiutute

At the Eternal Spring Institute, students are guided through a structured and progressive training system consisting of multiple levels: Apprentice, Intermediate, Advanced, Elite, and Disciple. Upon reaching the Disciple level, a student may be accepted as a closed-door disciple through the traditional Bai Si (tea ceremony), signifying a formal and deeply respected commitment to the lineage.

After approximately three to four years of dedicated and intensive training, eligible students may apply for private instruction and invitation-only closed group training. These advanced studies focus on refined internal development and long-term cultivation, deepening skill through advanced Qigong and Nei Gong methods, detailed study of the Kuen Kuit (fist poems) and their underlying principles, and practical applications intended to prepare students for responsible transmission and guidance of others.

Sifu Sergio’s Path
Sifu Sergio’s approach is shaped by decades of rigorous training across Hong Kong, China, Taiwan, Singapore, New Zealand, and Canada, blended with modern insights gained through sustained practice and deep personal exploration. His teaching method bridges classical tradition with contemporary understanding, allowing students to cultivate authentic internal strength, refined awareness, and lasting self-mastery in a way that is both traditional and highly functional.

Structure of the Program

The Eternal Spring Institute offers two complete and complementary internal Wing Chun training pathways, each grounded in the same core internal principles, while differing in scope, structure, and emphasis.

Internal Wing Chun Course

The Internal Wing Chun course is a fully developed and focused program, designed for Wing Chun practitioners from all lineages as well as committed beginners. This pathway places its primary emphasis on the Ancient 1700 Single Set Siu Lin Tau, using it as the central framework for developing structure, internal power, awareness, and functional application.

Through this form, students cultivate genuine internal skill, deepen their understanding of core principles, and experience meaningful internal development without needing to follow the full Apprentice-to-Disciple progression. This course offers a direct and effective entry into internal Wing Chun training while remaining compatible with other Wing Chun practices and life commitments.

1700 / 1800 Internal Wing Chun Curriculum

The 1700 / 1800 Internal Wing Chun Curriculum represents the complete traditional progression of internal Wing Chun training. Within this extended pathway, students are taught all major Wing Chun Kuen forms, including:
  • Siu Nim Tau
  • Chum Kiu
  • Biu Tze
  • The Ancient 1700 Single Set Siu Lin Tau
In addition, this curriculum includes specific ancestral Wing Chun forms preserved from the systems of the Wing Chun forebears responsible for the creation of the Ancient Single Set Siu Lin Tau. These forms provide historical context, technical depth, and a deeper understanding of the evolution and internal logic of the system.

This pathway is intended for practitioners seeking full immersion, progressing through all stages of internal training, classical forms, principles, and long-term cultivation as traditionally preserved within the lineage.

Both training pathways are authentic, rigorous, and highly valuable, sharing the same internal standards and principles, while offering different approaches to depth, structure, and long-term commitment.

1700 / 1800 Internal Wing Chun

The Eternal Spring Institute 1700 / 1800 Internal Wing Chun Online Program represents one of the two distinct pathways for online study within the Eternal Spring Institute’s educational structure. This pathway is formally integrated into multiple associations worldwide, for example within the Schools of Kung Fu departments of the IWKA, where it is taught in affiliated academies as the Eternal Spring Institute Master Classes, dedicated exclusively to the 1700 / 1800 Internal Wing Chun curriculum


For many years, students have been led to believe that it takes 20 years or more to develop high-level internal skill. In some cases, higher internal methods were deliberately withheld by teachers out of fear that students might surpass them. This misconception can now be laid to rest.

Through the Eternal Spring Institute 1700 / 1800 Internal Wing Chun Online Curriculum, Sifu Sergio Pascal Iadarola guides students through the exact internal cultivation process required to reach levels of internal development that once seemed unattainable. The program includes precise, detailed instruction in the Ancient Siu Lin Tau set, originally developed at the end of the 1700s, as well as the three-set format of Siu Nim Tau, Chum Kiu, and Biu Tze in their earliest known forms from their mid-1800s development, transmitted according to classical internal principles.

Around the world today, many claim to teach internal Wing Chun. Unfortunately, much of what is presented consists of empty choreography, devoid of real internal content. It has become increasingly difficult to find practitioners who demonstrate deep, authentic internal skill, and even more difficult to find teachers who preserve the correct Wing Chun forms capable of accommodating true internal development.

According to historical research, Wing Chun around the time of the Taiping Uprising was simplified and stripped of much of its internal content. One reason for this was the urgent need to prepare fighters quickly in order to overthrow the Qing dynasty and restore the Ming. As a result, many deeper internal methods were set aside or lost over time.

After decades of extensive research and training, Sifu Sergio Pascal Iadarola has resurrected the Ancient Siu Lin Tau (Little Training) set, working closely with his internal teachers to restore it precisely according to the Kuen Kuit. In parallel, together with his colleague Sifu Yuri Morelli, an official lineage holder in the Snake Crane Wing Chun lineage, he systemised and refined the syllabus of the earliest versions of Siu Nim Tau, Chum Kiu, and Biu Tze, based on the secret notes recorded by Law Tai Wan in 1890.

Even today, only a handful of masters worldwide are capable of teaching authentic internal Wing Chun from this period. Traditionally, these teachings were reserved for family members or closed-door disciples. Furthermore, through more than 16 years of living and training in China, Sifu Sergio has had the rare privilege of studying multiple lineages to completion, an opportunity afforded to very few.

The Eternal Spring Institute 1700 / 1800 Internal Wing Chun Online Program provides direct access to this preserved knowledge, eliminating the need for countless journeys around the world. Students are able to study authentic internal Wing Chun directly from Sifu Sergio, from the comfort of their own home or wherever they are, using modern online learning tools.

The founder of the Internal Wisdom and Knowledge Association, Sifu Sergio Pascal Iadarola, is proud to present this formal Institute-level online program, offering real internal transmission, structured progression, and lineage-based teaching within the Eternal Spring Institute.
"The internal martial arts is all about Mastering Body, Mind and Energy."
Sifu Sergio P. Iadarola
