What should be written on the calligraphy seal? Can those seals write their own names?

Two-word name: so-and-so shop, so-and-so seal, so-and-so painting name, etc.: so-and-so shop name: directly engraved with your own name. Specifically, there are many idle chapters that can be carved at will according to your own preferences, moods and allusions. For example, good as water, life is like a dream, easy to walk, there are too many rivers, and too many wild cranes in the clouds show their personality.
