From which poem does "the mountains are high and the clouds are the peaks" come?

The original sentence is taken from a couplet presented by a friend of Zhang Daqian, a master of Chinese painting, "The mountain is the highest man-made peak, and the sea is the end."

First, the original sentence is taken from the couplet presented by the friend of Zhang Daqian, a master of Chinese painting-"The mountain is the highest man-made peak, the sea ends, and the sky is the shore", which has a broad artistic conception.

"The top of the mountain" shows that as long as one is willing to climb, he can reach the realm of "climbing Mount Tai and making the world small".

Second, the extension:

There is also a saying that "the mountain is the peak, the sea is the sea, and the heart is unbounded".

There are the following couplets as evidence:

I am the peak-Lin Zexu.

At the end of the sea, the sky is the shore, the mountain is the highest, and the artificial peak is the highest-a friend gave it to Zhang Daqian.

Heaven never shuts one door but he opens another, earth never shuts one door but he opens another, and mountains never shuts one door but he opens another. I am the peak-Mount Tai in Wang Ne is extremely connected.
