The old man took photos at the seaside.

The old man hammered a nail in the seaside. Whenever he knocks on it, he seems to be talking to the sea and asking questions about the human mind. That nail is the embodiment of thought and the extension of language. It contains human history and civilization, and also represents wisdom and persistence. This story makes us think about the relationship between man and nature, and how to express those unspeakable feelings and experiences in words.
