This is a surprise. The Chinese form has been available for months now at http://www.thehum.info, and has been advertised on a few Chinese forums in Vancouver. Not one report has been entered. There are a few possibilities, in order of plausibility:
- Word has not spread. If I can get a few readers to post to forums in Hong Kong, this may cause discussion of the Hum to go viral and get the reports flooding in.
- My site is being filtered from web searches by the Chinese Firewall (this should be easy enough to check).
- The Hum does not occur in China (I find this highly unlikely, but it is possible).
