As a teacher, the main goal of the first calligraphy class is to fully explain the advantages of learning calligraphy and the disadvantages of not learning calligraphy.
In the first class, it is the key to stimulate students' strong interest in learning calligraphy. It didn't arouse students' interest in learning calligraphy, which was the most failed first class. After calligraphy class, some students may doze off.
Stimulating students' interest in learning calligraphy is a very successful first class, which makes students feel the desire to learn calligraphy actively. Even if you can't teach them calligraphy lessons for special reasons, they will explore their own calligraphy knowledge. Maybe in a few years, there will be one or two calligraphers among those who will listen to your successful class, and at least a few calligraphy lovers who have a strong interest in calligraphy.
After listening to such a successful calligraphy class forty years ago, I have never stopped exploring calligraphy knowledge for decades. Learning calligraphy not only cost me a lot of time, but also cost me a lot of money (buying famous books, rice paper, wool paper, writing brushes, etc. Although I didn't become a calligrapher, I can be regarded as a person who can write beautiful calligraphy in this respect.
