Tang Dynasty: Shi Jianwu
Open a green ghost and pour out a thousand springs. (hukāI qěng míng diān，Xiècháwàn zhàng quán .)
If you cut a grain, the sky will hang in autumn. (rúcáI yáo sáo，báI rìXun qi tiān .)
waterfall
The waterfall seems to have cracked a gap at the top of the blue sky, and the spring water fell from the sky. Another example is to cut a plain silk and float down from the crisp blue sky in autumn under the bright sunshine.
Like cutting a grain.
