「 横看成岭侧成峰，
远近高低各不同。
不识庐山真面目，
只缘身在此山中。 」
— 苏轼，《题西林壁》, 大约11世纪 ^[1]

^{[1] “Ridges in front and peaks to the side,
Mountains in different shapes far and wide.
Of Lushan’s true facade one can never know,
If one stays within the mountains so.”
— Su Shi, “Writing for Xilin Temple’s Wall,” translated by L. Y. Lee, circa 11th century}
