Peiyang University resumed its classes as soon as Japan surrendered in 1945. Meanwhile, the Ministry of Education ordered Peiyang University to take in the so-called “Polytechnic School of Peking University”, which was established on the original site of the Polytechnic School of Peking University during the Japanese occupation. Later, it was renamed as “Peking School of Peiyang University”, but Textile Department was still closed down. Suggested by Zhang Duoshan, professor at the former Department of Weaving of Peking University, and some other people, Peiyang University applied to the Ministry of Education for “restoring the original Textile Department at Peking School of the Peiyang University” in Tianjin, which was then approved. Subsequently, most of the staff memberts of the former Department of Weaving, the Polytechnic School of Peking University came back to Tianjin along with its books and reference materials. “By then, the oldest department of textile engineering in North China” finally settled in Peiyang University.
In 1951, Peiyang University was combined with Hebei University of Technology into Tianjin University, and their textile departments were also combined into Textile Department of Tianjin University.
