After the victory of the Anti-Japanese War, the Department of Electrical Engineering was moved back to the Tsinghua Campus together with Tsinghua University, and was allowed to enroll more than 100 freshmen that were most in all departments then. A saying went at that time, “the Department of Electrical Engineering is a most difficultly-entering department for students while the Department of Civil Engineering is a longest-serving one in Tsinghua University”.
