Du Mu repeatedly cited low wages as a reason for not being able to support his family, and suggested that he wanted to go to Hangzhou or Huzhou. Now scholars and experts do not agree that Du Mu's real reason is that the salary is too low, the main reason may still be his political views and the cattle party do not get along, not to be reused, in addition to the assassin Du Mu has been down there, may be more willing to go to do a term of office for the benefit of the party's magistrates, do not want to get involved in the political struggle, and is more willing to go to the people to do some real work. In 850 A.D., at the age of 47, Du Mu became the assassin of Huzhou.

Du Mu in Yangzhou, hanging out between the greenhouse, heard that Huzhou many beautiful women, went to Huzhou to play, the results of a young girl only ten years old, said to the other parents, I ten years later will come to Huzhou when the county governor, then I will marry her, if not, you will be married to someone else normally, but also paid a valuable bride price. At this time has passed ten years, Du Mu anxious to realize the promise, so strive to serve in Huzhou. But really to the post of Huzhou, the little girl has married someone else, and had a child. Du Mu to find his parents theory, the other side said that the ten years of the appointment has passed.

Now the wind swing flower wolf, green leaves into shade son full of branches".
