What you want to ask is why did University of Science and Technology Beijing Yanqing Branch stop doing it? The reason for this is the following：

1. Difficulties in running a school: Yanqing Branch faces many problems in running a school and its educational resources are limited. At the same time, the enrollment is small and difficult, which makes it difficult to run a branch school.

2. Adjust the development strategy: University of Science and Technology Beijing decided to readjust and optimize its own school layout to achieve high-quality development, so it will reconsider the problems of Yanqing Branch and finally decide not to enroll students.
