What is the content of the poem "Painting"? (Poets, authors and dynasties are also required)

Painting

Wang Wei, Tang Dynasty

From a distance, the mountains are colorful, but up close, the water is silent.

Spring has gone and the flowers are still there,

The birds are not surprised when people come.

Judging from the poetry, this painting contains mountains, water, flowers and birds, which is very freehand. After a few strokes, the painting was described as lifelike, almost like the real thing. Looking at the painting, it looks like a real mountain with colors from a distance. When I get closer, there is no sound. Spring has passed, but the flowers have not faded. Even if someone comes, the birds in the painting will not be scared away. There is poetry within the painting, and there is painting within the poetry.
