Dear chris : Thank you for your response. The blog was set up by accident while I was in a classroom for a demonstration to the medical students by a very popular active internet writer  during my visit to a medical school in Taipei. Anyway up to today I am still unable to write on the net in chinese.I am working on it. It may take a little while till I master the skill. Untile then please pay attetion to Miss Cheun's articles. You will sure enjoy them.
