Bamboo leaves are green but not proud, and smoke blows ink. Dance alone, send cool and shake the pen. What does this poem mean?

Bamboo leaves are green but not proud, and smoke blows ink. Dance alone, send cool and shake the pen.

This is a poem about bamboo.

It means: green bamboo, green bamboo leaves, covered by washed moonlight, like an ink painting with clouds intersecting. Whenever the slender bamboo branches dance after being blown by the night wind, the moonlight on the bamboo leaves breaks into thousands of mottled silver snakes, bringing a burst of coolness to the world.
