However, if you plan to let your children develop in this direction in the future, you should think carefully. As far as I am concerned, there are many people learning piano at present, and the later cost is high, and the input cost is high (for example, you need to ask a teacher for guidance when you take an examination of the Conservatory of Music). If you want to achieve higher results in this respect, it depends on your talent. Chinese painting (including calligraphy), Chinese opera, martial arts and Chinese medicine are all quintessence of the country, and I like them very much, but not many people learn them now, except calligraphy and martial arts. I studied for a few days because of the correct teacher's guidance and my own practice, because there are many problems, such as composition and brushwork. I remember that some Chinese painting tutorials of a teacher Huo in Tianjin were broadcast in the education station, and the teacher's name was forgotten.
