I want to know the answer to the following question:
What is the Chinese name for a seismometer?
All the background I'm provided with is that "Zhang called his device the 'instrument for measuring the seasonal winds and the movements of the Earth' (Houfeng didong yi 候风地动仪), so-named because he and others thought that earthquakes were most likely caused by the enormous compression of trapped air.". Is that enough to answer the question?
Answer: yes
