Coach Lee is still at C2 Badminton Club with his wife Young-Suk (former World #2 Womens Singles).
He is not listed as a C2 coach because he doesn't work under them as a coach - he has his own club within C2 Badminton (http://ccbadmintonclub.com/) and only rents their courts for his own private coaching.... similar to how E-Badminton books the courts as passmore for their own private coaching.
Thank you very much. Didn't realize this - very interesting. So wouldn't C2 coaches lose out on coaching fees to Coach Bok? Not familiar with this business model.
