Is drinking hard-pen calligraphy about growing up?

No, Into the Wine is a famous sentence by Li Bai, a poet in the Tang Dynasty. It expresses the lofty sentiments and aspirations for life and the attitude of pursuing freedom by self-talk. It is not hard-pen calligraphy, but a poem, usually presented in writing or recitation. Hard-pen calligraphy is a writing method, which uses a hard nib (such as a pen or brush) to write on paper. It pays attention to the accuracy and standardization of lines and is usually used in education, calligraphy practice and business writing. Therefore, "Into the Wine" is not a hard-pen calligraphy about growth.
