2, the water is ancient, and the ambition is outside the water. Li Bai's thoughts are Taoist. When he encounters setbacks in reality, he will find a spiritual habitat and release his dissatisfaction. For example, "On the Peach Blossom Spring, a thousand springs are separated by flowing water." (Antique) "Peach Blossom Flowing Water _ When it goes away, it is another world." (Q&A in the Mountain) These two poems use the allusions in Tao Yuanming's Peach Blossom Garden. Of course, peach blossoms and flowing water are not Li Bai's ideal. Looking forward to Xanadu is only a temporary comfort to oneself, and more is to express depression. It is Li Bai's favorite to set off the changes of the world with the unchanging water of ancient and modern times and write his own talents, and he can use it freely. For example, "Phoenix once played here, so this place is named after them, but now it is abandoned on this desolate river." (On Climbing Nanjing to Phoenix Terrace) The combination of the words "Phoenix goes to Taiwan empty" shows that Phoenix Terrace is now cold and lonely, and the prosperity of the Six Dynasties is gone. Only nature is the eternal reality. And "I am on this bridge, remembering the past and respecting the British style." I only saw running water, not Huang Shigong. "Zhang Zifang under the Piqiao Bridge in Xia Jing" is about the blue waves of Piqiao Bridge, which has never changed since ancient times. What has changed is that you can't have the chance to meet Huang Shigong in Sean, so as to express ingratitude. "Night Sleeping in Niuzhu" also uses the same technique: "Niuzhu Xijiang Moon, there is no cloud in the blue sky. Looking up at the moon, remembering the old general in vain. "Looking at the bright moonlight on the quiet and peaceful river, Li Bai thought that Justin, who" sings very high "on such a water surface, was appreciated by Xie Shang, a famous celebrity. Although he was outstanding in talent, no one appreciated him, and his melancholy was even more prominent.
