Xianzhou Liu

Liu He (;

After graduating in 1918, he returned to Hebei to teach at the middle school he had attended until 1921, and in 1924 he became president of Beiyang University. In 1928, he resigned as president of Beiyang University and became a professor at Northeastern University and head of the Department of Engineering. After the Japanese invasion of Manchuria on September 18, 1931, Liu came to teach at Tsinghua University. He continued to teach in Beijing until the Marco Polo Bridge Incident of July 7, 1937, when he followed Tsinghua University's relocation to the Southwest and taught at the National Southwestern Associated University until the end of the war in 1945. He visited the United States in 1946-1947, and upon his return from that visit, he continued to teach at Tsinghua University.

He was very loyal to the Chinese Communist Party, but he was still dissatisfied with the Great Leap Forward and the Cultural Revolution, and was persecuted during the Cultural Revolution. In 1970, he drafted his own work plan for the next 10 years even though he suffered from a number of serious illnesses, and died in October 1975 of pancreatic cancer in the Third Affiliated Hospital of the Beijing Medical University.

Legacy Liu is well known for his research into the literature on the development of machinery and machines in ancient China. He also compiled numerous mechanical engineering terminology.
