A Busan teacher makes weekly volunteering part of his work
Seo Chang-deok’s KNN interview describes a youth teaching commitment that followed a bank-supported program in 2025.

A one-off youth program became a continuing commitment for Busan yoga teacher Seo Chang-deok. In a November 12 KNN interview, he says he has taught middle and high school students weekly as a volunteer since early 2026.
A regular place in the week
Seo traces that work to a youth program supported by Busan Bank the previous year. He also describes three years of volunteering in addiction facilities in cooperation with a Japanese yoga association.
The interview connects his community work with his preference for teaching that responds to an individual’s circumstances, rather than giving everyone an identical set of movements and breathing instructions.
These details come from Seo’s own account on KNN’s People Focus program. The broadcast does not provide an independently evaluated study of the weekly classes, so his enthusiasm about their effects cannot establish a treatment outcome.
The narrower story is the continuity of the work. A teacher returns each week to a group of young people, while describing plans to extend his volunteering. The interview supplies no confirmed new timetable or expansion date. Its practical contribution is a view of volunteer teaching as an ongoing responsibility rather than a single public event.
