Is the personnel of Yantai Highway Bureau decided by the municipal government or the provincial highway bureau?

What you said is not entirely right. Yantai Highway Bureau was originally a subordinate unit of Yantai Transportation Bureau, and was later taken over by the Highway Bureau. His business and personnel belong to the vertical leadership of the provincial bureau, that is, to the provincial highway bureau However, in terms of traffic control, it is under the jurisdiction of Yantai Transportation Bureau or under the dual jurisdiction of Yantai Transportation Bureau and Provincial Highway Bureau. As for why there is inconsistency between the superior and the subordinate, this is the current system problem in China, not only the expressway system, but also others. For example, Yantai Salt Bureau, originally a subordinate unit of Yantai No.1 Light Bureau, was taken over by the Provincial Salt Bureau and jumped up at once. No one can explain this.
