In the Heron Tower is a poem by Wang Zhihuan, a poet in the Tang Dynasty. The whole poem is as follows: the mountains cover the day, and the ocean drains the golden river. 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. Poet critics in Qing Dynasty thought: "Wang's poems are just two crosses, the first cross has done its best, and the last cross has a thousand miles." This poem is a masterpiece of five-character poems in Tang Dynasty. Wang Zhihuan is famous for this five-character quatrain, and the mirage is also famous in China.
