Jiang Xue appreciated the first sentence.

There are no birds flying over those mountains, and there are no traces of people in those paths. First of all, the poet used the words "Qianshan" and "Wanjing" to set off the following two pictures of "boating alone" and "fishing alone". Without the words "thousand" and "ten thousand", the words "loneliness" and "independence" at the back will appear bland and uninspiring. Secondly, birds flying on the mountain and people walking on the road are very common things and the most general image. But the poet put them under the "Qianshan" and "Wanjing" and added the word "absolutely" and "extinct", which suddenly turned the most common and summarized dynamic into extreme silence and absolute silence, forming an unusual scene.
