Twelve-month calligraphy signature

As far as I know, the twelve months and months in calligraphy works are usually signed with an elegant name instead of directly writing numbers. The elegant names of twelve months are: early year, half spring, late spring, early summer, midsummer, late summer, early autumn, clear autumn, late autumn, early winter, frosty moon and old age. These appellations not only reflect the tradition and aesthetic feeling of China culture, but also enrich the calligraphy works.
