Zhou's Ph. D. from CalTech is in general relativity. His view started to xxxx after ten years studies of relativity when Einstein failed to answer his question on coordinates. His has a collection of work on general relativity. His achievements are cited in the Chinese Academy of Science. Currently, Zhou is well-known for his achievement on fluid dynamics. He also have a foundation that give scholarships to students.

On the contrary, as far as I can find, Yang has written only one paper on general relativity.

My work is well documented in journals and the library for preprints.
