Today, I became the president of the high school calligraphy club. The club started today, and no one in it knew me. What should I say when I go in? What should I do? How to teach?

Greet everyone warmly first, be humorous and cheerful when introducing yourself, and leave a good impression on everyone. Then let everyone introduce themselves briefly, and then you can tell them your future plans in this calligraphy club, and then you can start your calligraphy course.
