Zhengding county. According to Baidu map information, the predecessors of Beijing Institute of Technology and North China College of China Renmin University are located in Zhengding County, Shijiazhuang City, Hebei Province. North China University has nurtured a number of institutions of higher learning in New China. During the period from 1948 to 1949, in order to meet the needs of the great development of culture and education, some subordinate units gradually separated from the school to run schools independently, and the Institute of Technology independently developed into Beijing Institute of Technology. Agricultural College merged with Peking University Agricultural College and Tsinghua University Agricultural College to form Beijing Agricultural University. Two foreign languages departments left the school and merged with Beiping Foreign Affairs School to form Beiping Foreign Languages School, and then gradually developed into Beijing Foreign Studies University.
