Read the following three materials and answer the following questions.

Material 1: At present, many primary and secondary schools have been occupied by other courses due to the pressure of entering higher schools. In addition, although there are some schools with calligraphy characteristics in the city, they often only pay attention to the cultivation and competition of special students, which may not benefit all students. Therefore, it has become very common for middle school students to write badly, can't write, make mistakes and can't recognize traditional Chinese characters. Material 2: In Japan, calligraphy is generally listed as a compulsory course for primary and secondary schools. South Korea, on the other hand, plans to declare "Calligraphy" as the intangible cultural heritage of mankind, and replace "China Calligraphy" and "Japanese Calligraphy" with this name. At the beginning of this year, this news caused a lot of heated discussion. Zhao, a member of the Chinese People's Political Consultative Conference and a writer, submitted a proposal entitled "Declaration of China Calligraphy to the United Nations as an Intangible Cultural Heritage of Humanity" at the National "Two Sessions", which was responded by many deputies. Material 3: Calligraphy includes aesthetic forms such as brush and ink lines, structure and layout. A writer must coordinate his heart, eyes and hands. Without the participation of willpower, it is difficult to persist in calligraphy practice. Therefore, practicing calligraphy is conducive to the psychological growth and personality improvement of young people. In addition, writing brush strokes can activate or wake up the cerebral cortex, which has the function of improving intelligence. Question: (1) Please draw up a general title for these three materials and briefly analyze the reasons. (2) Students will hold a special issue of "Calligraphy Culture". Please recommend two materials to them.
