The learning content is different and the teaching staff is different.
1. Learning content. Major classes usually have more systematic and comprehensive teaching plans, including basic theoretical knowledge, calligraphy techniques and practical operations. Non-major courses may need to find teaching materials and learning resources on their own, and require more time and energy to accumulate experience and skills.
2. Teachers. Subject classes usually have professional teachers and complete teaching facilities, which can provide students with more professional and systematic teaching services. Non-major classes may need to find suitable teachers themselves or obtain teaching resources through online platforms.
