Ding Lei's resume says University of Electronic Science and Technology of China, but it is actually Chengdu University of Electronic Science and Technology of China. Chengdu Dianzi University always wanted to change its name to Dianzi University, but Xi 'an didn't agree, so it hasn't changed. However, the English name UESTC of Chengdu Dianzi University has long been changed. As for which major Ding Lei studied, communication engineering is written on his resume, but in fact he studied electronic information engineering and electronic display direction.
