Do adults need training classes to learn Chinese calligraphy?

It varies from person to person. If you want to go to a training class, you can also teach yourself, such as watching related tutorials online and so on.

Brush calligraphy is a unique traditional art in China. Throughout the ages, Chinese characters in China have been created by working people, and began to be shown in the form of pictures. After thousands of years of development, it has evolved into today's writing. In ancient times, writing with a brush for a long time produced calligraphy. Chinese characters are mainly written with a brush. As for other writing forms, their writing rules are not completely different from those of the brush, but they are basically the same.
