But what's the next sentence when you expand your horizons by 300 miles and go up a storey still higher?

"Going up a storey still further broadens the horizon by 300 miles", which means that if you want to see the scenery of thousands of miles, you must climb to a higher height. If you want to achieve greater success, you must make more efforts. If you want to make a breakthrough on a certain issue, you can look at it from a higher angle. From Don Wang Zhihuan's Heron Hostel.

Whole poem:

The sun sets slowly near the western hills, and the Yellow River flows into the East China Sea.

By going up one flight of stairs, look further.

The first two sentences of this poem are about natural scenery, but when you start writing, you will shrink Wan Li at your fingertips, so that you can have Wan Li at your fingertips. The last two sentences are freehand brushwork, written unexpectedly, and integrate philosophy with scenery and situation seamlessly. The poet's mind, under the shock of nature, has realized a simple and profound philosophy, which can urge people to abandon the superficial knowledge of complacency, climb high and look far, and constantly open up new and better realms.
