I want to learn a talent now. Which is easier to learn in college, guzheng, Chinese or calligraphy?

See which one you are interested in or which one you are good at. Learning guzheng can make you happy. As a student, you should see if the price of guzheng is acceptable. It's easy to learn calligraphy by yourself, but you need to copy it yourself and cultivate its connotation. Language is more practical, especially small languages. It is not a talent but a second major.
