Cao Hao is a special friend.  We grew up together, and our family have a good relationship.  He knows a lot about computer (in many aspects, more than I do) & he has a broad mind and high personal goals.   It's nice to have him in Wuhan near my parents 'cause sometimes he's the fastest way for my family to get in touch with me.  It would be nice, too,  if we can re-unite here in the U.S.  Guess someday we will.
