He returned to China in 1952 and that year became professor of Department of Physics at Tsinghua University, Peking University and the University of Science and Technology of China. He joined the Jiusan Society. In 1953, he became a researcher at the Institute of Geophysics, Chinese Academy of Sciences, where he was deputy director in 1978. He was accepted as an academician of the Chinese Academy of Sciences in 1980. In September 2005, he was hired as a part-time professor at the Graduate College of Chinese Academy of Sciences.[5][6]
On August 19, 2018, he died of illness at Beijing, aged 98.[5]
