Although Xi 'an University of Posts and Telecommunications is recruiting students, its comprehensive strength is not strong. The reason why it is placed in a batch of enrollment is mainly related to the subject characteristics of Xiyou Post and its position in Xi 'an (the specialty of Xiyou Post is highly compatible with the fiery mobile communication industry, with good employment and high employment quality). The strength of Lanzhou University is far above that of Xi University of Posts and Telecommunications, but it is still in the second batch of enrollment. The reason is nothing more than two reasons: the areas and industries involved in the major are relatively hard.
