Generally, you need to invest 50,000 to 100,000. Depending on the area, if it is a county town, it may be lower. After all, you can invest a lot less in rent and decoration.

Calligraphy and calligraphy practice are recognized by national policies and are also fully valued in primary and secondary schools.
