今年5月我收到了慕尼黑大學附屬醫院Stief院長的來信，他正在非洲南部高原的喀拉哈里沙漠旅行，那里常常停電，又沒有網。此刻的他遠離塵囂，足以忘憂。他的人生實在是太驚艷了。你我應當把生命當作是一場冒險，讓寶石般的烈火在胸中熊熊燃燒。你若讀懂了真正的大師，你才能讀懂真正的人生。天地初寒，大雪為章；恰逢其時，紛至人間；冬來無恙，雪墜為念；不懼流年，不慌不忙；且聽、且看、且從容；且停、且忘、且隨風。2023年圣誕佳節又一次來了。我們有61位中國醫生在德國著名大學附屬醫院攻讀臨床醫學MD博士和開展博士后研究。這三年的時光德國大學附屬醫院各學科帶頭人首次讓中國醫生可以成為他們的博士生，可以與他們一起開展博士后研究。一位普通醫生要成長為優秀醫生，未來甚至可以成為頂級醫生。一位普通醫生要成長為優秀醫生，未來甚至可以成為頂級醫生。他們只有學習、學習再學習，終生學習，終生向大師學習。學習學科的規范，手術的技巧，全球思考的理念。這才是快速成功的源泉。勃蘭登堡門靜靜地立在萬里之外。我想念德國，想念我們的醫生，想念我們的朋友。想念德國的大城小鎮，想念哥廷根的圣誕集市，想念在阿德龍飯店的晚餐。伊薩爾河靜靜地流著。我想念你們，圣誕快樂，冬日情長，光陰無恙。 

This year in May, I got a letter from Prof. Stief, Deputy Medical Director of University Hospital of Munich. He was traveling in Kalahari Desert of Southern African Highlands, where power frequently goes out and there is no internet access. At that time, he was away from the human society and forgot all the worries. He is living such a fulfilling life. You and I shall see our lives as an adventure and let the gem-like enthusiasm burn bright in our hearts. When you really understand the true masters, you can understand the real meaning of life. The Greater Snow marks the beginning of coldness. The snow arrives at the right time naturally. Hope you are sound in winter, and greet you with the falling snow. Fleeting time will never makes us anxious. We shall take our time to appreciate the scenery, and let the worries go with the wind. Christmas of 2023 is coming. aWe have sent 61 Chinese doctors to renowned university hospitals in Germany to pursue their M.D. study and do postdoctoral research. For the last three years, the academic leaders of each specialty from German university hospitals have received Chinese doctors for the first time as their doctoral students and postdoctoral researchers.  If a common doctor wants to grow into an excellent one, and even a top one in the future, The only way is to learn, keep learning for a lifetime, and learn from the great doctors. The key to achieving success quickly is to learn standardized specialty knowledge, surgical techniques, and global thinking. Brandenburg Gate stands quietly thousands of miles away. How I miss Germany, our doctors, and our friends. How I miss the cities and towns of Germany, the Christmas market in G?ttingen, and the dinner at Lorenz Adlon Restaurant. The Isar River flows tranquilly. Miss you all, and merry Christmas. Love in the winter lasts, and we are sound despite the flowing time.
