She became a professor of physics at the National Taiwan University. From 1981 to 1983 she was the head of the department of physics at the university. As of 2019 she is the only woman to hold this role. Whilst she was in charge, she arranged an audit of the department, and it was found that a radioactive source that was meant to be stored safely was missing. The newspapers reported the problem, and it was only when national bodies became involved that the radium - beryllium neutron source was found. She wanted to concentrate on teaching, so she stood down from her management role. She continued to teach for twenty years, and she was cited as a role model for other women to study physics.
