Which is better for a 15-year-old girl to learn Latin dance or calligraphy? Folk dance? Taekwondo?

Folk dance is better. Folk dance can meet the needs of basic dance skills without being too strenuous. Among all dance categories, Latin dance has relatively low requirements for basic skills. In contrast, the basic requirements of folk dance are not as strong as ballet. It is within the child's adaptable range, can meet the child's certain dance needs, and can play a role in strengthening the body. If you have enough time, you can practice calligraphy. The most important thing is to see which one the child likes. After all, interest is the best motivation.
