已届86岁高龄的南开大学资深教授、著名历史学家、中国现代史奠基人之一的魏宏运教授学识渊博,学养深厚,为国内外史学家所敬慕。然而,很少有人知道,早在求学期间,魏宏运已经投身于革命事业,成为一名中共地下党员,为北平、天津顺利解放贡献了一份力量。 The 86-year-old senior professor and famous historian of Nankai University, Professor Wei Hongyun, one of the founders of the modern history of China, is a highly educated and profound student and adored by historians at home and abroad. However, few people know that as early as during the study period, Wei Hongyun has devoted himself to the cause of revolution and has become an underground party member of the Chinese Communist Party, contributing a force to the smooth liberation of Peiping and Tianjin.
