纳凉 — "taking the coolness" — is the Chinese summer practice of sitting outside in the evening when the air cools. No task, no purpose, just the cooling of the air and the appearance of fireflies. Chinese culture had a word for this because it was considered worth doing deliberately.

The summer evening asks for nothing. Just sit. Let the air cool. That is enough.

Not every hour needs a purpose. Some hours are for cooling off in the summer evening.
