Xing Shan wrote a corresponding poem.

Mutu's Mountain Walk: In the distance, there are people from Bai Yunsheng. Stop and sit in the maple forest late, and the frost leaves are red in February flowers. Du Mu was the 13th in the family, so he was called "Du Thirteen" according to the custom of the Tang Dynasty. Du Mu's political talent is outstanding. As a teenager, he crusaded against the buffer region in Tang Xianzong, inspiring the state affairs. After studying, he cares about the army. Later, Du Mu specialized in Sun Tzu's Art of War, wrote thirteen articles about Sun Tzu's Art of War, and wrote many policy addresses. Especially on one occasion, it was adopted by Prime Minister Li Deyu, and it was a great success.

In the second year of Huichang (842), he was released as the secretariat of Huangzhou. The reason why Du Mu was released is not recorded in the history books. Du Mu thought it was the exclusion of Prime Minister Li Deyu. Du Li's two families are family friends. Why doesn't Li Deyu want Mu? Some people think that Du Mu is charming and informal, which is inconsistent with Li Deyu's philosophy. In addition, there is also a struggle between Niu and Li. Du Mu has a good personal relationship with Niu's monks and Confucian scholars, and Li Deyu may think that they are one side.
