Is it a liar for the teacher of University of Electronic Science and Technology of China to call in advance?

No, every year when colleges and universities enroll students, the teachers of the college enrollment group may call the candidates who apply for their own schools to ask some questions, or ask students to modify their volunteer opinions. You can't be a liar without asking for sensitive information or paying. University of Electronic Science and Technology of China is located in Chengdu, the capital of Sichuan Province, directly under the Ministry of Education of People's Republic of China (PRC), and is jointly established by the Ministry of Education, the Ministry of Industry and Information Technology, Sichuan Province and Chengdu.
