Before introducing yourself, put a video of yourself practicing yoga, and then introduce yourself. You can make your own data into PPT in the form of multimedia. Including your basic information, such as name, age, place of origin, etc. Then introduce how many years of yoga teaching experience I have, how many students I have taught, what achievements I have made and what awards I have won. If you can, you can find some former students and put their comments on teachers in the form of videos.
