From Dr. Lam: For any certified instructor, you can use my online lesson, to coordinate yourself to guide your participants. This can be the most effective and fulfilling way to teach tai chi under this challenging situation, because my online lessons and DVDs are designed with a lot of research, experience and effort to be most user friendly, like my class format. Your personal knowledge and experience are the best for your people, combining both would be most effective. People would benefit greatly from regular guidance, encouragement and feedback this way.
