Beijing University of Posts and Telecommunications is a first-class university, with 2 1 1 engineering and double-class construction. It is a national key university directly under the Ministry of Education, which is the key construction of the Ministry of Industry and Information Technology. So Beijing University of Posts and Telecommunications is not 985, but 2 1 1.
The "985 Project" refers to the major decision made by the China Communist Party, the people of China and the State Council to build a world-class university at the turn of the century. The first batch of "985 Project" built nine universities, namely, Peking University, Tsinghua University, China University of Science and Technology, Fudan University, Shanghai Jiaotong University, Xi Jiaotong University, Nanjing University, Zhejiang University and Harbin Institute of Technology, which were later approved.
