Dear Dr. Sanbar's family, This is shocking news! I received a WeChat message as recent as January 21, 2021 from Dr. Sanbar. I never heard of him talking about his own health issue and that was why I was so shocked when I received the news. Dr. Sanbar was a great man and great friend of China! I have learned a lot from his optimism, wisdom, intelligence and modesty during the past 15 years I have known him. Dr. Sanbar will always live in the hearts and minds of his Chinese friends! My profound condolences to the family of Dr. Sanbar! Most sincerely, Jack H. Shi
