The first thing we need to know is calligraphy, poetry and Beijing Opera. It is not only a hobby, but also a profession. In ancient times, many people studied poetry, calligraphy and Peking Opera. Because of their hobbies and because it was a means of making a living, many people made a living in this line. Since you want to make a living, of course, you should publicize it vigorously, because anything related to eating is valued by people. Moreover, in ancient times, people didn't have much entertainment, so these poems, calligraphy and Peking Opera were more popular. On the other hand, modern occupations and means can help people make a living. Numerous poems, calligraphy and Peking Opera are more of a hobby, so fewer and fewer people are engaged in this line and fewer and fewer people are exposed to these things.
Moreover, under the influence of modern culture, poetry, calligraphy and economy are no longer the cultural pursuit of the public. What people like now is some fast food culture, which is timely and exciting. Can stimulate people's sensory pursuit. Poetry, calligraphy, Peking Opera and other spiritual cultures have not been completely abandoned. But only a small number of people are willing to spend a small part of their time studying this culture.
In addition, poetry, calligraphy, economy and other cultures are more complicated to learn. And it is not the mainstream of modern culture. If you want to learn poetry, calligraphy and Peking Opera well, you will spend a lot of time and energy, which is not in line with modern exam-oriented education. Learning poetry, calligraphy and Peking Opera is not very good for exam-oriented education. On the contrary, many parents think that learning these cultures will affect their children's academic performance, so in the long run, few people are willing to accept these poems, calligraphy and Peking Opera, and thus gradually decline and gradually move away from the public.
