Why did Taihu County, Anqing County, Guoyang County and Sihong County dismiss the posts of special animal epidemic prevention commissioners?

First of all, when recruiting for this position, it is labor dispatch. Although exams are required, it is compiled informally. So this understanding is the government's work needs in a certain period of time. Now it may be the cost or the progress of the work, and it is found that similar positions are no longer needed. Therefore, dismissal is also reasonable.
