This page contains some of my random logs of my studies, researches, ideas and thoughts. They are only my personal views (and political position, if any), and have nothing to do with the my students, my department and the Chinese University of Hong Kong.
The blogs may be written in either Chinese (中文) or English, or both. I apologize for the inconvenience caused, and please let me know in case an alternative version in a different language is needed.
