Is calligraphy the same as classic courses and legal system?

It's different. With different definitions and purposes, calligraphy and classic lessons belong to the category of culture and art, and are the pursuit and expression of culture, aesthetics and language. The legal system belongs to the category of political and social order, and it is a norm and constraint on power, obligation and responsibility. Inheritance and development are different: the inheritance and development of calligraphy and classic courses mainly depend on cultural traditions and personal cultivation, while the formulation and implementation of the legal system depends on the national legal system and government agencies.
