Here are two photos we took with Mrs Yuen when she last visited Hong Kong in the winter of 1998. We had tea together in Maxim Restaurant in Causeway Bay. She looked quite fine at that time.   The other scan is the the last Christmas card I received from Mrs. Yuen in December 2000. Her words on the card showed that she loved her friends and colleagues although they are separated from two different hemispheres. You see, she really treasures the happy time with us both at CCSC and meetings in Hong Kong.   Please put them in your home-page so that CCSC students or teachers can see them.   -- S. S. Wat
